Cone crusher is a kind of common equipment in the production line of sand and gravel aggregate in mines. It is mainly used for two-stage crushing and three-stage crushing in metal mines and sand and gravel aggregate processing. Because of its strong crushing capacity and large output, it is widely used in the crushing operation of medium hard materials.

Cone crusher can be divided into spring type, hydraulic type and compound type according to different structural devices.

1. Spring cone crusher

Spring cone crusher adopts spring safety system as overload protection device, which can make foreign matters pass through the crushing chamber without harming the machine. * The equipment works reliably and is mainly used in some crushing production processes that do not have too high requirements on particle shape.

2. Hydraulic cone crusher

Hydraulic cone crusher, with hydraulic cylinder, is divided into single cylinder cone crusher, multi cylinder cone crusher and full hydraulic cone crusher. It is suitable for sand production lines with strict requirements on product grain shape and high degree of automation.

3. Compound cone crusher

Compound cone crusher is composed of spring device and hydraulic cylinder. Single cylinder hydraulic cone breaker has good intermediate crushing effect and large passing capacity; The multi cylinder hydraulic cone has better crushing effect and high content of fine materials; If the spring cone is broken, it can not be fully fed, and the processing capacity is low; The automatic adjustment of the discharge port cannot be realized.

Maintenance of cone crusher

1. Single cylinder cone breaker has simple structure, low failure rate, low production cost and more stable operation;

2. All parts of multi cylinder cone can be disassembled and maintained from the top or side, making daily replacement more convenient;

3. It takes a long time to repair the broken spring cone, which is difficult to maintain.

4. The hydraulic cone crusher has the advantages of simple structure, low manufacturing cost, high production capacity, easy maintenance, excellent hydraulic adjustment and overload protection, especially easy to realize automatic control.
