Understanding material behavior, belt interaction and system dynamics can significantly reduce wear, spillage and maintenance costs.

<p>The post How to engineer better conveyor performance first appeared on Pit & Quarry.</p>

Loading conveyors properly in a quarry is critical to the long-term health of belts and systems, as well as overall safety and efficiency.

Sharp and heavy raw materials dropping vertically and unobstructed onto a belt are not the only factors that reduce belt life and break rolling components. Varying sizes of conveyed material – including aggregates, sand and slurry – each present unique loading issues at various stages throughout the transport cycle.

Improper belt loading signs

No two operations are alike. Failure to consider all aspects of design will result in unnecessary dust, spillage and generally shorter belt and equipment life.

When designing a loading zone, engineers should account for several elements, including natural material movement, material adhesiveness, material distribution, material interaction with the belt, bulk density, and safety and maintenance.

1. Natural material movement. Some chute designs have rock boxes or shelves that slow the descent of cargo, but these can result in clogging or sudden surges when deposits of material break free.

Flat chutes can produce splashing and backflow that damage components, resulting in spillage, dust and uncentered belt loading. A curved design better controls material flow and remedies these issues by slowing the descent and centering the cargo.

2. Material adhesiveness. In some operations, factors such as moisture, magnetic qualities, silica content and the direction of the metal grain on the surface of chute walls can contribute to chute plugging and excessive downtime.

Clogs may not occur immediately. Instead, the weight of buildup may cause a sudden surge that overwhelms the loading zone.

3. Material distribution. To determine how soon a belt should be troughed after the tail pulley – and at what angle – engineers rely on the surcharge angle, which is one at which material naturally settles in relation to the belt once it forms a stable profile.

4. Material interaction with the belt. Improper loading of small, sharp materials like crushed stone and gravel can produce significant dust and spillage along walkways, fouling the return side of the belt and becoming entrapped between the skirtboard and belt. This can result in belt damage.

Uneven loading can cause the belt path to shift, causing mistracking and spillage along the entire length of the system.

5. Bulk density. The loose bulk density is the weight per unit of volume of material in a noncompacted condition. Although the consolidated bulk density of some materials can cause the troughed cargo to condense into a much smaller size, once the particulates separate in the transfer chute at the point of discharge, the volume can increase considerably.

So, loose bulk density should be recalculated and used to determine the geometry of each transfer point based on this change.

6. Safety and maintenance. Labor and safety issues for monitoring and maintaining the flow of material can be costly if overlooked.

When receiving cargo from other conveyors, feeders, front loaders or railcars, the paramount concern in any design should be safety. This is achieved by controlling throughput, impeding obstructions and sealing the chute to prevent spillage and dust.

Belt support

Installed directly under the chute discharge, impact cradles alleviate belt damage by absorbing the forces from material landing on the belt.

Many operators are moving away from impact idlers in favor of static cradles that feature a bed of steel angles lined by energy-absorbing impact bars with a top layer of low friction, ultra-high molecular weight polymer or polyurethane.

The space between impact idlers can create a small gap between the skirtboard and the belt. The impact of material on the belt can cause a splashing effect of fines and produce air turbulence that seeks exit points from the chute through these gaps, pulling dust and spillage with it. The bar design retains a consistent seal at the loading point to reduce the amount of spillage and dust emissions.

Takeaways

Load zone design is not an exact science. With so many considerations, some details inevitably get missed.
Until a system is up and running, engineering design can only provide highly informed scientific estimates that may change. Unpredictable factors such as weather, foundation settling and variations in material density can affect post-construction operations and efficiency.

Luckily, there is equipment specifically designed to mitigate these design issues and engineered to fit any system retroactively. It is only through experience, observation and testing – and some smart engineering – that the correct retrofit can be applied.

In his latest Going Home Safely, Every Day column, Steve Fuller details common types of fall protection and how producers can avoid them.

<p>The post How to eliminate fall hazards around your operation first appeared on Pit & Quarry.</p>

Remember way back to my inaugural column last November when I detailed how hazards can be grouped into an acronym called “GEMS?”

Three of these four hazards – gravity, electrical and mechanical – are everywhere you look in pits and quarries. These can be very impactful to health and well-being.

That said, let’s dive into “gravity” as it relates to fall protection.

What is fall protection

Fall protection is simply employing safeguards within your work environment to help prevent you from falling to a lower level.

I’ve seen people struggle with understanding when fall protection is required. Legally, the thresholds vary.

For scaffolding, it’s 10 ft.; for construction work, 6 ft.; for general industry, 4 ft.; and for manlifts or work around crushers, fall protection is technically required at any height.

I advise clients not to get caught up in that regulatory game. Just use a common-sense approach to protecting employees from any fall. Some of the most serious injuries I’ve seen have occurred even from ground level.

Common types of fall protection

• Guardrails. Guardrail systems around a fixed plant are the most common type of fall protection I’ve seen in crushing plants.

Guardrails consist of a toe kick, a mid-rail and a top rail – but these could also be a continuous piece of metal mesh. Make sure these are in good shape, as plants take a beating from the elements, vibration and other factors.

Your daily mine inspection should note any deficiencies so they can be corrected immediately. Also, know that if you get on a ladder or scaffolding and thereby raise your elevation, the guardrail may become ineffective – meaning you’ll need additional fall protection.

• Aerial lifts. These are an excellent tool – when used correctly.

Aerial lifts can eliminate the need for scaffolding, ladders and working in an unsafe way to attain height.
While aerial lifts have built-in guardrails, those are not sufficient for fall protection if an aerial lift is mobile. If a moving aerial lift hits a rock, debris or another object, it could catapult you out of the basket.

This is why you always need to wear fall protection in a mobile aerial lift – regardless of how elevated the lift is. I have investigated several events where employees were thrown from the basket. The outcome is a devastating one.

• Engineered systems. By far, the two most common methods of fall protection I’ve seen in pits and quarries are guardrails and aerial lifts.

I’ve seen scenarios requiring additional engineering to solve – like working on top of pieces of mobile equipment that don’t have guardrails. In this specific case, we pulled the mobile equipment into a maintenance bay and engineered a system into the ceiling with retractable lanyards and beam clamps.

Just know you should consult an engineer when creating these systems, as you must ensure you have at least 3,000 lbs. of anchorage strength when using work positioning systems – and 5,000 lbs. when using fall protection systems.

These systems, which include harnesses, lanyards and engineered connection points and lines, must be inspected and often have expiration dates you must adhere to.

What to avoid

I’ve investigated a lot of falls over the past two decades, and they all have one thing in common: shortcuts were taken.

Here are a few items to seek out and not permit into your organization:

• Standing on guardrail systems

• Ascending and descending ladders or stairs with your hands full

• Attaining height through unapproved means (i.e., standing on chairs, standing on top of trucks, standing in loader buckets)

• Jumping to a lower level

• Using a stepladder in the closed position

• Not wearing a harness/lanyard while in an aerial lift

• Using a straight/extension ladder without having it secured (i.e., either footed by a team member or tied off

Final thoughts

To the supervisors and team leaders reading this: I encourage you to use this article at your next toolbox talk with your team.

Ask your team if they have any common work evolutions that give them concern. Talking about hazards leads to solutions.

I also encourage you to pay extra attention to your guardrail systems during your next daily zone inspection.

As Motion Industries describes, the lube caddy delivers a fast, efficient and clean way to service a facility’s enclosed gearing assets while enhancing worker safety – and it is also compatible with hydraulic systems.

The lube caddy’s features include a dual-design reservoir and an auto shutoff mode that prevents the pump from running dry when the tank empties. Options are available for 40- and 75-gallon oil capacities, enabling sanitary and seamless oil changes without the need for multiple containers. A 150-gallon hoistable version is also available.

Additionally, three operation modes are available: manual, auto and kidney loop. The air-operator pump offers automatic shutoff, allowing hands-off operation while the process runs safely.

According to Motion, the lube caddy is suitable for manufacturers that change lubrication oil periodically – particularly for gearboxes, hydraulic systems and more.

“Our team regularly builds unique solutions to fulfill customer needs, but it’s not often we decide to make one a standard product,” says Scott Smith, West Division Manager at Motion Repair & Services. “What started as a vision evolved into a solid solution that can serve a wide range of industries. The cart’s mobility, compact footprint and integrated design let maintenance teams bring it directly to equipment – no hoses trailing back to a shop, no spills, no drums, no filter carts and no wasted time.”

Understanding material behavior, belt interaction and system dynamics can significantly reduce wear, spillage and maintenance costs.

<p>The post How to engineer better conveyor performance first appeared on Pit & Quarry.</p>

Loading conveyors properly in a quarry is critical to the long-term health of belts and systems, as well as overall safety and efficiency.

Sharp and heavy raw materials dropping vertically and unobstructed onto a belt are not the only factors that reduce belt life and break rolling components. Varying sizes of conveyed material – including aggregates, sand and slurry – each present unique loading issues at various stages throughout the transport cycle.

Improper belt loading signs

No two operations are alike. Failure to consider all aspects of design will result in unnecessary dust, spillage and generally shorter belt and equipment life.

When designing a loading zone, engineers should account for several elements, including natural material movement, material adhesiveness, material distribution, material interaction with the belt, bulk density, and safety and maintenance.

1. Natural material movement. Some chute designs have rock boxes or shelves that slow the descent of cargo, but these can result in clogging or sudden surges when deposits of material break free.

Flat chutes can produce splashing and backflow that damage components, resulting in spillage, dust and uncentered belt loading. A curved design better controls material flow and remedies these issues by slowing the descent and centering the cargo.

2. Material adhesiveness. In some operations, factors such as moisture, magnetic qualities, silica content and the direction of the metal grain on the surface of chute walls can contribute to chute plugging and excessive downtime.

Clogs may not occur immediately. Instead, the weight of buildup may cause a sudden surge that overwhelms the loading zone.

3. Material distribution. To determine how soon a belt should be troughed after the tail pulley – and at what angle – engineers rely on the surcharge angle, which is one at which material naturally settles in relation to the belt once it forms a stable profile.

4. Material interaction with the belt. Improper loading of small, sharp materials like crushed stone and gravel can produce significant dust and spillage along walkways, fouling the return side of the belt and becoming entrapped between the skirtboard and belt. This can result in belt damage.

Uneven loading can cause the belt path to shift, causing mistracking and spillage along the entire length of the system.

5. Bulk density. The loose bulk density is the weight per unit of volume of material in a noncompacted condition. Although the consolidated bulk density of some materials can cause the troughed cargo to condense into a much smaller size, once the particulates separate in the transfer chute at the point of discharge, the volume can increase considerably.

So, loose bulk density should be recalculated and used to determine the geometry of each transfer point based on this change.

6. Safety and maintenance. Labor and safety issues for monitoring and maintaining the flow of material can be costly if overlooked.

When receiving cargo from other conveyors, feeders, front loaders or railcars, the paramount concern in any design should be safety. This is achieved by controlling throughput, impeding obstructions and sealing the chute to prevent spillage and dust.

Belt support

Installed directly under the chute discharge, impact cradles alleviate belt damage by absorbing the forces from material landing on the belt.

Many operators are moving away from impact idlers in favor of static cradles that feature a bed of steel angles lined by energy-absorbing impact bars with a top layer of low friction, ultra-high molecular weight polymer or polyurethane.

The space between impact idlers can create a small gap between the skirtboard and the belt. The impact of material on the belt can cause a splashing effect of fines and produce air turbulence that seeks exit points from the chute through these gaps, pulling dust and spillage with it. The bar design retains a consistent seal at the loading point to reduce the amount of spillage and dust emissions.

Takeaways

Load zone design is not an exact science. With so many considerations, some details inevitably get missed.
Until a system is up and running, engineering design can only provide highly informed scientific estimates that may change. Unpredictable factors such as weather, foundation settling and variations in material density can affect post-construction operations and efficiency.

Luckily, there is equipment specifically designed to mitigate these design issues and engineered to fit any system retroactively. It is only through experience, observation and testing – and some smart engineering – that the correct retrofit can be applied.

In his latest Going Home Safely, Every Day column, Steve Fuller details common types of fall protection and how producers can avoid them.

<p>The post How to eliminate fall hazards around your operation first appeared on Pit & Quarry.</p>

Remember way back to my inaugural column last November when I detailed how hazards can be grouped into an acronym called “GEMS?”

Three of these four hazards – gravity, electrical and mechanical – are everywhere you look in pits and quarries. These can be very impactful to health and well-being.

That said, let’s dive into “gravity” as it relates to fall protection.

What is fall protection

Fall protection is simply employing safeguards within your work environment to help prevent you from falling to a lower level.

I’ve seen people struggle with understanding when fall protection is required. Legally, the thresholds vary.

For scaffolding, it’s 10 ft.; for construction work, 6 ft.; for general industry, 4 ft.; and for manlifts or work around crushers, fall protection is technically required at any height.

I advise clients not to get caught up in that regulatory game. Just use a common-sense approach to protecting employees from any fall. Some of the most serious injuries I’ve seen have occurred even from ground level.

Common types of fall protection

• Guardrails. Guardrail systems around a fixed plant are the most common type of fall protection I’ve seen in crushing plants.

Guardrails consist of a toe kick, a mid-rail and a top rail – but these could also be a continuous piece of metal mesh. Make sure these are in good shape, as plants take a beating from the elements, vibration and other factors.

Your daily mine inspection should note any deficiencies so they can be corrected immediately. Also, know that if you get on a ladder or scaffolding and thereby raise your elevation, the guardrail may become ineffective – meaning you’ll need additional fall protection.

• Aerial lifts. These are an excellent tool – when used correctly.

Aerial lifts can eliminate the need for scaffolding, ladders and working in an unsafe way to attain height.
While aerial lifts have built-in guardrails, those are not sufficient for fall protection if an aerial lift is mobile. If a moving aerial lift hits a rock, debris or another object, it could catapult you out of the basket.

This is why you always need to wear fall protection in a mobile aerial lift – regardless of how elevated the lift is. I have investigated several events where employees were thrown from the basket. The outcome is a devastating one.

• Engineered systems. By far, the two most common methods of fall protection I’ve seen in pits and quarries are guardrails and aerial lifts.

I’ve seen scenarios requiring additional engineering to solve – like working on top of pieces of mobile equipment that don’t have guardrails. In this specific case, we pulled the mobile equipment into a maintenance bay and engineered a system into the ceiling with retractable lanyards and beam clamps.

Just know you should consult an engineer when creating these systems, as you must ensure you have at least 3,000 lbs. of anchorage strength when using work positioning systems – and 5,000 lbs. when using fall protection systems.

These systems, which include harnesses, lanyards and engineered connection points and lines, must be inspected and often have expiration dates you must adhere to.

What to avoid

I’ve investigated a lot of falls over the past two decades, and they all have one thing in common: shortcuts were taken.

Here are a few items to seek out and not permit into your organization:

• Standing on guardrail systems

• Ascending and descending ladders or stairs with your hands full

• Attaining height through unapproved means (i.e., standing on chairs, standing on top of trucks, standing in loader buckets)

• Jumping to a lower level

• Using a stepladder in the closed position

• Not wearing a harness/lanyard while in an aerial lift

• Using a straight/extension ladder without having it secured (i.e., either footed by a team member or tied off

Final thoughts

To the supervisors and team leaders reading this: I encourage you to use this article at your next toolbox talk with your team.

Ask your team if they have any common work evolutions that give them concern. Talking about hazards leads to solutions.

I also encourage you to pay extra attention to your guardrail systems during your next daily zone inspection.

For scaffolding, it’s 10 ft.; for construction work, 6 ft.; for general industry, 4 ft.; and for manlifts or work around crushers, fall protection is technically required at any height.

I advise clients not to get caught up in that regulatory game. Just use a common-sense approach to protecting employees from any fall. Some of the most serious injuries I’ve seen have occurred even from ground level.

Common types of fall protection

• Guardrails. Guardrail systems around a fixed plant are the most common type of fall protection I’ve seen in crushing plants.

Guardrails consist of a toe kick, a mid-rail and a top rail – but these could also be a continuous piece of metal mesh. Make sure these are in good shape, as plants take a beating from the elements, vibration and other factors.

Your daily mine inspection should note any deficiencies so they can be corrected immediately. Also, know that if you get on a ladder or scaffolding and thereby raise your elevation, the guardrail may become ineffective – meaning you’ll need additional fall protection.

• Aerial lifts. These are an excellent tool – when used correctly.

Aerial lifts can eliminate the need for scaffolding, ladders and working in an unsafe way to attain height.
While aerial lifts have built-in guardrails, those are not sufficient for fall protection if an aerial lift is mobile. If a moving aerial lift hits a rock, debris or another object, it could catapult you out of the basket.

This is why you always need to wear fall protection in a mobile aerial lift – regardless of how elevated the lift is. I have investigated several events where employees were thrown from the basket. The outcome is a devastating one.

• Engineered systems. By far, the two most common methods of fall protection I’ve seen in pits and quarries are guardrails and aerial lifts.

I’ve seen scenarios requiring additional engineering to solve – like working on top of pieces of mobile equipment that don’t have guardrails. In this specific case, we pulled the mobile equipment into a maintenance bay and engineered a system into the ceiling with retractable lanyards and beam clamps.

Just know you should consult an engineer when creating these systems, as you must ensure you have at least 3,000 lbs. of anchorage strength when using work positioning systems – and 5,000 lbs. when using fall protection systems.

These systems, which include harnesses, lanyards and engineered connection points and lines, must be inspected and often have expiration dates you must adhere to.

What to avoid

I’ve investigated a lot of falls over the past two decades, and they all have one thing in common: shortcuts were taken.

Here are a few items to seek out and not permit into your organization:

• Standing on guardrail systems

• Ascending and descending ladders or stairs with your hands full

• Attaining height through unapproved means (i.e., standing on chairs, standing on top of trucks, standing in loader buckets)

• Jumping to a lower level

• Using a stepladder in the closed position

• Not wearing a harness/lanyard while in an aerial lift

• Using a straight/extension ladder without having it secured (i.e., either footed by a team member or tied off

Final thoughts

To the supervisors and team leaders reading this: I encourage you to use this article at your next toolbox talk with your team.

Ask your team if they have any common work evolutions that give them concern. Talking about hazards leads to solutions.

I also encourage you to pay extra attention to your guardrail systems during your next daily zone inspection.

Understanding material behavior, belt interaction and system dynamics can significantly reduce wear, spillage and maintenance costs.

<p>The post How to engineer better conveyor performance first appeared on Pit & Quarry.</p>

Loading conveyors properly in a quarry is critical to the long-term health of belts and systems, as well as overall safety and efficiency.

Sharp and heavy raw materials dropping vertically and unobstructed onto a belt are not the only factors that reduce belt life and break rolling components. Varying sizes of conveyed material – including aggregates, sand and slurry – each present unique loading issues at various stages throughout the transport cycle.

Improper belt loading signs

No two operations are alike. Failure to consider all aspects of design will result in unnecessary dust, spillage and generally shorter belt and equipment life.

When designing a loading zone, engineers should account for several elements, including natural material movement, material adhesiveness, material distribution, material interaction with the belt, bulk density, and safety and maintenance.

1. Natural material movement. Some chute designs have rock boxes or shelves that slow the descent of cargo, but these can result in clogging or sudden surges when deposits of material break free.

Flat chutes can produce splashing and backflow that damage components, resulting in spillage, dust and uncentered belt loading. A curved design better controls material flow and remedies these issues by slowing the descent and centering the cargo.

2. Material adhesiveness. In some operations, factors such as moisture, magnetic qualities, silica content and the direction of the metal grain on the surface of chute walls can contribute to chute plugging and excessive downtime.

Clogs may not occur immediately. Instead, the weight of buildup may cause a sudden surge that overwhelms the loading zone.

3. Material distribution. To determine how soon a belt should be troughed after the tail pulley – and at what angle – engineers rely on the surcharge angle, which is one at which material naturally settles in relation to the belt once it forms a stable profile.

4. Material interaction with the belt. Improper loading of small, sharp materials like crushed stone and gravel can produce significant dust and spillage along walkways, fouling the return side of the belt and becoming entrapped between the skirtboard and belt. This can result in belt damage.

Uneven loading can cause the belt path to shift, causing mistracking and spillage along the entire length of the system.

5. Bulk density. The loose bulk density is the weight per unit of volume of material in a noncompacted condition. Although the consolidated bulk density of some materials can cause the troughed cargo to condense into a much smaller size, once the particulates separate in the transfer chute at the point of discharge, the volume can increase considerably.

So, loose bulk density should be recalculated and used to determine the geometry of each transfer point based on this change.

6. Safety and maintenance. Labor and safety issues for monitoring and maintaining the flow of material can be costly if overlooked.

When receiving cargo from other conveyors, feeders, front loaders or railcars, the paramount concern in any design should be safety. This is achieved by controlling throughput, impeding obstructions and sealing the chute to prevent spillage and dust.

Belt support

Installed directly under the chute discharge, impact cradles alleviate belt damage by absorbing the forces from material landing on the belt.

Many operators are moving away from impact idlers in favor of static cradles that feature a bed of steel angles lined by energy-absorbing impact bars with a top layer of low friction, ultra-high molecular weight polymer or polyurethane.

The space between impact idlers can create a small gap between the skirtboard and the belt. The impact of material on the belt can cause a splashing effect of fines and produce air turbulence that seeks exit points from the chute through these gaps, pulling dust and spillage with it. The bar design retains a consistent seal at the loading point to reduce the amount of spillage and dust emissions.

Takeaways

Load zone design is not an exact science. With so many considerations, some details inevitably get missed.
Until a system is up and running, engineering design can only provide highly informed scientific estimates that may change. Unpredictable factors such as weather, foundation settling and variations in material density can affect post-construction operations and efficiency.

Luckily, there is equipment specifically designed to mitigate these design issues and engineered to fit any system retroactively. It is only through experience, observation and testing – and some smart engineering – that the correct retrofit can be applied.

In his latest Going Home Safely, Every Day column, Steve Fuller details common types of fall protection and how producers can avoid them.

<p>The post How to eliminate fall hazards around your operation first appeared on Pit & Quarry.</p>

Remember way back to my inaugural column last November when I detailed how hazards can be grouped into an acronym called “GEMS?”

Three of these four hazards – gravity, electrical and mechanical – are everywhere you look in pits and quarries. These can be very impactful to health and well-being.

That said, let’s dive into “gravity” as it relates to fall protection.

What is fall protection

Fall protection is simply employing safeguards within your work environment to help prevent you from falling to a lower level.

I’ve seen people struggle with understanding when fall protection is required. Legally, the thresholds vary.

For scaffolding, it’s 10 ft.; for construction work, 6 ft.; for general industry, 4 ft.; and for manlifts or work around crushers, fall protection is technically required at any height.

I advise clients not to get caught up in that regulatory game. Just use a common-sense approach to protecting employees from any fall. Some of the most serious injuries I’ve seen have occurred even from ground level.

Common types of fall protection

• Guardrails. Guardrail systems around a fixed plant are the most common type of fall protection I’ve seen in crushing plants.

Guardrails consist of a toe kick, a mid-rail and a top rail – but these could also be a continuous piece of metal mesh. Make sure these are in good shape, as plants take a beating from the elements, vibration and other factors.

Your daily mine inspection should note any deficiencies so they can be corrected immediately. Also, know that if you get on a ladder or scaffolding and thereby raise your elevation, the guardrail may become ineffective – meaning you’ll need additional fall protection.

Although the consolidated bulk density of some materials can cause the troughed cargo to condense into a much smaller size, once the particulates separate in the transfer chute at the point of discharge, the volume can increase considerably.

So, loose bulk density should be recalculated and used to determine the geometry of each transfer point based on this change.

6. Safety and maintenance. Labor and safety issues for monitoring and maintaining the flow of material can be costly if overlooked.

When receiving cargo from other conveyors, feeders, front loaders or railcars, the paramount concern in any design should be safety. This is achieved by controlling throughput, impeding obstructions and sealing the chute to prevent spillage and dust.

Belt support

Installed directly under the chute discharge, impact cradles alleviate belt damage by absorbing the forces from material landing on the belt.

Many operators are moving away from impact idlers in favor of static cradles that feature a bed of steel angles lined by energy-absorbing impact bars with a top layer of low friction, ultra-high molecular weight polymer or polyurethane.

The space between impact idlers can create a small gap between the skirtboard and the belt. The impact of material on the belt can cause a splashing effect of fines and produce air turbulence that seeks exit points from the chute through these gaps, pulling dust and spillage with it. The bar design retains a consistent seal at the loading point to reduce the amount of spillage and dust emissions.

Takeaways

Load zone design is not an exact science. With so many considerations, some details inevitably get missed.
Until a system is up and running, engineering design can only provide highly informed scientific estimates that may change. Unpredictable factors such as weather, foundation settling and variations in material density can affect post-construction operations and efficiency.

Luckily, there is equipment specifically designed to mitigate these design issues and engineered to fit any system retroactively. It is only through experience, observation and testing – and some smart engineering – that the correct retrofit can be applied.

In his latest Going Home Safely, Every Day column, Steve Fuller details common types of fall protection and how producers can avoid them.

<p>The post How to eliminate fall hazards around your operation first appeared on Pit & Quarry.</p>

Remember way back to my inaugural column last November when I detailed how hazards can be grouped into an acronym called “GEMS?”

Three of these four hazards – gravity, electrical and mechanical – are everywhere you look in pits and quarries. These can be very impactful to health and well-being.

That said, let’s dive into “gravity” as it relates to fall protection.

What is fall protection

Fall protection is simply employing safeguards within your work environment to help prevent you from falling to a lower level.

I’ve seen people struggle with understanding when fall protection is required. Legally, the thresholds vary.

For scaffolding, it’s 10 ft.; for construction work, 6 ft.; for general industry, 4 ft.; and for manlifts or work around crushers, fall protection is technically required at any height.

I advise clients not to get caught up in that regulatory game. Just use a common-sense approach to protecting employees from any fall. Some of the most serious injuries I’ve seen have occurred even from ground level.

Common types of fall protection

• Guardrails. Guardrail systems around a fixed plant are the most common type of fall protection I’ve seen in crushing plants.

Guardrails consist of a toe kick, a mid-rail and a top rail – but these could also be a continuous piece of metal mesh. Make sure these are in good shape, as plants take a beating from the elements, vibration and other factors.

Your daily mine inspection should note any deficiencies so they can be corrected immediately. Also, know that if you get on a ladder or scaffolding and thereby raise your elevation, the guardrail may become ineffective – meaning you’ll need additional fall protection.

• Aerial lifts. These are an excellent tool – when used correctly.

Aerial lifts can eliminate the need for scaffolding, ladders and working in an unsafe way to attain height.
While aerial lifts have built-in guardrails, those are not sufficient for fall protection if an aerial lift is mobile. If a moving aerial lift hits a rock, debris or another object, it could catapult you out of the basket.

This is why you always need to wear fall protection in a mobile aerial lift – regardless of how elevated the lift is. I have investigated several events where employees were thrown from the basket. The outcome is a devastating one.

• Engineered systems. By far, the two most common methods of fall protection I’ve seen in pits and quarries are guardrails and aerial lifts.

I’ve seen scenarios requiring additional engineering to solve – like working on top of pieces of mobile equipment that don’t have guardrails. In this specific case, we pulled the mobile equipment into a maintenance bay and engineered a system into the ceiling with retractable lanyards and beam clamps.

Just know you should consult an engineer when creating these systems, as you must ensure you have at least 3,000 lbs. of anchorage strength when using work positioning systems – and 5,000 lbs. when using fall protection systems.

These systems, which include harnesses, lanyards and engineered connection points and lines, must be inspected and often have expiration dates you must adhere to.

What to avoid

I’ve investigated a lot of falls over the past two decades, and they all have one thing in common: shortcuts were taken.

Here are a few items to seek out and not permit into your organization:

• Standing on guardrail systems

• Ascending and descending ladders or stairs with your hands full

• Attaining height through unapproved means (i.e., standing on chairs, standing on top of trucks, standing in loader buckets)

• Jumping to a lower level

• Using a stepladder in the closed position

• Not wearing a harness/lanyard while in an aerial lift

• Using a straight/extension ladder without having it secured (i.e., either footed by a team member or tied off

Final thoughts

To the supervisors and team leaders reading this: I encourage you to use this article at your next toolbox talk with your team.

Ask your team if they have any common work evolutions that give them concern. Talking about hazards leads to solutions.

I also encourage you to pay extra attention to your guardrail systems during your next daily zone inspection.

Understanding material behavior, belt interaction and system dynamics can significantly reduce wear, spillage and maintenance costs.

<p>The post How to engineer better conveyor performance first appeared on Pit & Quarry.</p>

Loading conveyors properly in a quarry is critical to the long-term health of belts and systems, as well as overall safety and efficiency.

Sharp and heavy raw materials dropping vertically and unobstructed onto a belt are not the only factors that reduce belt life and break rolling components. Varying sizes of conveyed material – including aggregates, sand and slurry – each present unique loading issues at various stages throughout the transport cycle.

Improper belt loading signs

No two operations are alike. Failure to consider all aspects of design will result in unnecessary dust, spillage and generally shorter belt and equipment life.

When designing a loading zone, engineers should account for several elements, including natural material movement, material adhesiveness, material distribution, material interaction with the belt, bulk density, and safety and maintenance.

1. Natural material movement. Some chute designs have rock boxes or shelves that slow the descent of cargo, but these can result in clogging or sudden surges when deposits of material break free.

Flat chutes can produce splashing and backflow that damage components, resulting in spillage, dust and uncentered belt loading. A curved design better controls material flow and remedies these issues by slowing the descent and centering the cargo.

2. Material adhesiveness. In some operations, factors such as moisture, magnetic qualities, silica content and the direction of the metal grain on the surface of chute walls can contribute to chute plugging and excessive downtime.

Clogs may not occur immediately. Instead, the weight of buildup may cause a sudden surge that overwhelms the loading zone.

3. Material distribution. To determine how soon a belt should be troughed after the tail pulley – and at what angle – engineers rely on the surcharge angle, which is one at which material naturally settles in relation to the belt once it forms a stable profile.

4. Material interaction with the belt. Improper loading of small, sharp materials like crushed stone and gravel can produce significant dust and spillage along walkways, fouling the return side of the belt and becoming entrapped between the skirtboard and belt. This can result in belt damage.

Uneven loading can cause the belt path to shift, causing mistracking and spillage along the entire length of the system.

5. Bulk density. The loose bulk density is the weight per unit of volume of material in a noncompacted condition. Although the consolidated bulk density of some materials can cause the troughed cargo to condense into a much smaller size, once the particulates separate in the transfer chute at the point of discharge, the volume can increase considerably.

So, loose bulk density should be recalculated and used to determine the geometry of each transfer point based on this change.

6. Safety and maintenance. Labor and safety issues for monitoring and maintaining the flow of material can be costly if overlooked.

When receiving cargo from other conveyors, feeders, front loaders or railcars, the paramount concern in any design should be safety. This is achieved by controlling throughput, impeding obstructions and sealing the chute to prevent spillage and dust.

The space between impact idlers can create a small gap between the skirtboard and the belt. The impact of material on the belt can cause a splashing effect of fines and produce air turbulence that seeks exit points from the chute through these gaps, pulling dust and spillage with it. The bar design retains a consistent seal at the loading point to reduce the amount of spillage and dust emissions.
