In the aggregates industry, downtime isn’t just inconvenient—it’s expensive.
Whether you’re processing sand, gravel, limestone, recycled aggregates or quarry materials, every minute of unplanned downtime impacts production, delivery schedules and profitability. With equipment operating in some of the harshest environments imaginable, reliability isn’t a luxury; it’s essential.
The good news is that many breakdowns are preventable with the right maintenance strategy and the right engineering partner.
Don’t Wait for Bearings to Fail
Bearings are one of the most common causes of unexpected plant downtime.
Constant exposure to dust, vibration, heavy loads and moisture can significantly reduce bearing life if they’re not correctly specified and maintained.
Regular inspections can help identify early warning signs, including:
- Excessive vibration
- Unusual noise
- Rising operating temperatures
- Grease leakage
- Visible wear
Replacing a bearing during planned maintenance is far less costly than dealing with a catastrophic failure during production.
Keep Lubrication Under Control
Lubrication is critical in preventing premature wear.
Using the correct grease or lubricant, applying it at the right intervals and avoiding over-greasing can significantly extend the life of bearings, conveyors and rotating equipment.
Many lubrication-related failures are entirely preventable.
Reduce Dust Ingress
Dust is unavoidable in aggregate processing—but it doesn’t have to damage your equipment.
Effective sealing, regular cleaning and maintaining dust extraction systems all help prevent contaminants entering bearings, gearboxes and other critical components.
Keeping dust under control doesn’t just improve reliability—it also creates a safer working environment.
Carry Critical Spares
When a conveyor stops unexpectedly, waiting for replacement parts isn’t an option.
Holding essential maintenance items on-site can dramatically reduce repair times, including:
- Bearings
- Belts
- Motors
- Gearboxes
- Chain
- Lubricants
- Pneumatic components
Working with a trusted supplier to identify critical spares can minimise downtime when failures do occur.
Check Conveyor Components Regularly
Conveyors are the backbone of many aggregate operations.
Routine inspections of rollers, idlers, belts, pulleys and drive systems help identify wear before it develops into a costly breakdown.
Small issues caught early often prevent much larger repairs later.
Plan Maintenance Around Production
Reactive maintenance is always more expensive than planned maintenance.
Scheduling inspections during planned shutdowns allows worn components to be replaced before they fail, helping avoid unexpected interruptions during busy production periods.
A proactive maintenance strategy improves reliability and makes maintenance budgets more predictable.
Work with an Engineering Partner – Not Just a Supplier
The right supplier does more than deliver products.
They help identify the correct components for demanding applications, recommend improvements, provide technical advice and ensure critical products are available when they’re needed.
At Leicester Bearings, we support businesses across the aggregates sector with:
- Bearings and bearing housings
- Conveyor components
- Managed Inventory solutions that help give engineers their time back
Keep Your Plant Moving
Reducing downtime isn’t about one single improvement—it’s about making lots of small improvements that add up to greater reliability.
By combining preventative maintenance with quality components, technical expertise and dependable stock availability, aggregate producers can reduce costly breakdowns and keep production moving.
At Leicester Bearings, we’ve been helping UK industry do exactly that for over 40 years.
