Cone crusher is suitable for crushing ore and rock which is above 300MPa hardness. It has 
Advantages of reliable structure, high production efficiency, easy to modulate, high cost- 
Effective. Its spring insurance system is the protecting gear for overload; This system can 
Make foreign matter pass the crushing cavity, but not damage the machine, using dry and 
Water two sealing type, it can segregate rock powder and lubricant, to ensure reliable 
Operation. The crushing cavity type is decide by ore's purpose, normal type is used for 
Medium crushing, medium type is used for fine crushing, short type is used for fine 
Crushing. 
Features 

1. High productivity; High quality 
2. Less machine stop time 
3. Easy maintenance and low cost 
4. Unique crushing ability in primary, secondary and tertiary crushing 
Principles 
The cone crusher consist of frame, transmission device, hollow eccentric shaft, bowl- 
Shaped bearing, crushing cone, springs and hydraulic pressure station for adjusting 
Discharge opening. 

During operation, the motor drives the eccentric shaft shell to turn around through a 
Horizontal axle and a pair of bevel gear. The axle of crushing cone swings with the force 
Of eccentric shaft shell so that the surface of the crushing wall is close to the roll 
Mortar wall from time to time. In this way, the ores and rocks will be pressed and crooked 
And crushed.
