Description

The PY series Cone Crusher has been developed to crush high or medium hardness material, such as iron ore ,copper ore, limestone, quartz, granite, and sand stones, etc., in metallurgical, construction, road building, chemical, silicate Industries. This crusher has the advantage of reliable construction, high prod activity, easy adjustment and less cost in operation. Standard type is for PYZ (secondary crush); middle type is for PYD (tertiary crush); short-head type is for primary and secondary crush. Working principle of Cone Crusher :
The 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 ahorizontal 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.
