Cone Crusher Detailed Explanation

1. Working principle of cone crusher
Cone crushers crush materials through the swinging motion of the moving cone inside the fixed cone, subjecting materials to continuous extrusion, bending, and shearing. Classified by cavity type: standard (medium crushing), medium (medium-fine), and short head (fine crushing), suitable for medium and fine crushing of hard rocks.

2. Hydraulic system and intelligent control function
Hydraulic systems of modern cone crushers have multiple functions:
– Overload protection: Hydraulic cylinders retract automatically when encountering uncrushable materials
– Auto chamber clearing: Raise the moving cone via hydraulics to remove jams quickly.
– Auto discharge adjustment: PLC system adjusts hydraulic pressure in real-time based on feeding to stabilize output size.

3. Selection comparison and application scenarios
Selection recommendations:
– Jaw crusher: For primary crushing of large materials, low initial investment.
– Impact crusher: For medium crushing and shaping, good product shape, suitable for construction stone.
– Cone crusher: For fine crushing of hard rocks, long wear life, suitable for large mines with continuous operation.

4. Maintenance points
– Regularly inspect the eccentric bushing wear of cone crusher, recommend disassembly every 500 hours.
– Replace hydraulic oil every 3000 hours, cleaning the tank and filter when replacing.
– Check the locking device of the adjusting ring and supporting ring regularly to avoid discharge opening changes due to looseness.
