Daily Maintenance Methods of Three Roll Crusher

Pre-operation Inspection

1. Check the gap between three rolls to ensure finished particle size meets standard, adjust in time if loose.
2. Inspect roller surface for material adhesion, wear and cracks, keep roller teeth intact.
3. Check tightness of belts and chains, ensure all safety guards are firmly installed.
4. Confirm sufficient lubricating oil level, tighten all anchor bolts.
5. Clean sundries at feeding inlet to avoid material blocking.

Operation Maintenance

1. Start the machine with no load, start feeding materials stably after normal operation.
2. Feed materials evenly, strictly prevent hard objects like iron and stones from entering the machine.
3. Keep observing machine running condition, stop operation once abnormal noise and severe vibration occur.
4. Stop power supply completely before clearing blocked materials, never clean materials during running.
5. Regularly check finished material uniformity, adjust equipment timely if there is any deviation.

Post-shutdown Maintenance

1. Cut off power thoroughly, clean residual feed inside the machine completely to prevent mildew and caking.
2. Wipe dust and oil stains on machine surface to keep equipment clean and tidy.
3. Clean residual materials in feeding and discharging pipes and hoppers.
4. Check flexibility of buffer spring mechanism, lubricate and derust if stuck.

Regular Lubrication

1. Inject high-temperature resistant grease into bearings every week; add grease every 3 days for high-speed running parts.
2. Apply lubricating oil on gap adjusting screw rods and slide rails weekly for flexible adjustment.
3. Clean dust and add engine oil on transmission sprockets and chains every half month.
4. Replace gear oil of reducer regularly in accordance with operation manual.

Wearing Parts Maintenance & Replacement

1. Repair or replace crushing rollers when teeth are severely worn.
2. Replace deformed or fractured buffer springs immediately.
3. Change aging sealing parts and dustproof sleeves to prevent dust from entering bearings.
4. Tension loose driving belts timely, replace cracked and damaged belts directly.

Common Fault Prevention

1. Excessive dust: check sealing structure and clean dust removal device regularly.
2. Unstable particle size: fasten gap adjusting components, prevent roll gap offset.
3. Severe vibration: level the machine body, reinforce foundation, inspect damaged bearings.
4. Overhigh temperature: avoid overloading feeding, enhance ventilation and ensure sufficient lubrication.

Long-term Shutdown Storage

1. Thoroughly clean all materials and dust inside and outside the machine.
2. Apply anti-rust oil on roller surfaces and exposed metal parts.
3. Cut off total power supply, cover the machine well and store in dry and ventilated place.
