How to Maintain the Cone Crusher‑Crusher Machine

As a high‑efficiency secondary and tertiary crushing device widely adopted in mines, aggregate quarries and solid‑waste recycling plants, the Cone Crusher undertakes medium‑fine crushing of hard rock and mineral ore. Scientific, regular maintenance is essential to reduce unexpected breakdowns, extend service life of wearing parts and keep the whole crushing‑screening line operating at optimal productivity. Neglecting daily inspection will easily trigger equipment jamming, sharp drop of output and extra‑high maintenance costs.

1. Pre‑start‑up Inspection Before Every Shift

Before turning on your cone‑crushing unit, carry out a comprehensive visual check. Inspect lubrication‑oil level, oil‑pipeline sealing status and oil‑cooling system to avoid poor lubrication which may cause burning of main shaft and bearing. Check tightness of all bolt fasteners, examine wear condition of mantle, concave and other vulnerable components. Clear away foreign materials inside the crushing cavity. Verify that the adjustment ring, hydraulic cylinder and safety‑protection device work normally. Never launch the machine with hidden faults.

2. On‑Operation Monitoring During Production

Keep observing the cone crusher’s running state after feeding ore. Pay close attention to unusual vibration, abnormal noise and sudden temperature rise of lubricating oil. Maintain even and stable feeding, ensure raw materials are distributed in the center of crushing cavity. Over‑feeding or eccentric feeding will lead to overload, uneven liner abrasion and frequent spring‑safety‑system triggering. If strange symptoms occur, stop feeding materials first and then shut‑down the equipment for troubleshooting.

3. Lubrication System Maintenance

The lubrication system is the core guarantee for stable operation. Replace lubricant oil on schedule according to operating hours. Filter or change oil once it becomes dirty or deteriorated. Clean oil filter element regularly. Check the oil return pipeline to prevent blockage. Proper lubrication greatly lowers friction between main‑shaft, bushing and frame, avoiding severe thermal‑locking accidents.

4. Periodic Replacement of Wearing Spare Parts

Mantle, concave, thrust bearing and locking bolt are fast‑worn components. Check their abrasion loss periodically. Replace liners before they are worn‑out completely, otherwise finished particle size will go out‑of‑specification and the equipment may suffer structural damage. When installing new wearing parts, ensure firm, balanced assembly to prevent loosening during long‑time crushing work.

5. Post‑shutdown Care and Long‑term Storage Maintenance

After finishing daily production, clean residual rock materials stuck inside the crushing chamber. Conduct a full‑inspection of key components. If the cone crusher will stay idle for a long period, apply anti‑rust treatment on exposed metal surfaces, drain lubrication oil and cover the whole machine with waterproof protective cloth.

6. Common Mistakes to Avoid in Daily Maintenance

Do not dismantle hydraulic‑safety components without professional technical guidance. Never adjust the discharge‑gap while ore materials remain inside the cavity. Avoid using mismatched spare parts from unknown suppliers, poor‑quality accessories will cause premature failure of your cone crusher.
