Preventive maintenance for crushers and screens: a practical checklist

Crushing equipment works in dust, vibration and shock loads every day. A short routine of planned checks prevents most breakdowns and extends the life of expensive wear parts. Always follow the manufacturer's manual for your machine; the list below is a general guide.

Safety first

Before any inspection, stop the machine, isolate and lock out the power source, and make sure moving parts have come to rest. Never clear a blockage in a crusher chamber while the machine is running.

Every shift

• Walk around the machine and look for leaks, loose bolts, damaged guards and cracked welds
• Check engine oil, coolant, hydraulic oil and fuel levels on mobile units
• Check lubrication on bearings and the crusher lubrication system (oil level, temperature, pressure)
• Inspect conveyor belts for damage, tracking and spillage
• Listen for unusual noise or vibration and report it
• Clean radiators and air filters in dusty conditions

Every week

• Measure wear on jaw plates, mantles, concaves or blow bars and record it
• Check the crusher setting and adjust for wear
• Inspect screen media for holes, blinding and loose tensioning
• Check V-belt tension and condition
• Grease points as specified by the manufacturer
• Test emergency stops and pull-wires

Periodically

• Change engine, hydraulic and lubrication oils and filters at the stated hours
• Sample oil to detect early wear
• Inspect bearings, shafts and the crusher frame for cracks
• Check undercarriage, tracks and rollers on tracked units
• Review wear-part consumption to plan stock and reduce downtime

Plan spare parts

Keep the parts that stop production on site or quickly available: wear liners, screen media, belts, filters and common hydraulic hoses. Recording hours and wear rates makes ordering predictable.
