Stone Cone Crusher
Cone crusher of PYF series, widely used in the industries of metallurgy, building material, road construction, chemical engineering & silicate, is suitable for crushing all kinds of ores and rocks with hardness of medium or above. This machine features the high crushing ratio, high efficiency, high handling capacity, low operation cost, easy adjustment and economical operation. The quality of material used for components and reasonable design of construction contributes to its longer running performance and even granularity of the crushed product in addition to reducing the circulation load; And furthermore by introducing the hydraulic cleaning chamber system into the crushers of middle and large size. The down time is reduced accordingly. The user may choose different type of chamber upon different request freely, because of the wide range of products to be provided.

This machine adopts grease sealing so as to prevent the watering and draining system from being blocked and avoid the defect of easy mix of water and oil. The spring safety system is the protection unit against overload, and keeps the crushing chamber from being damaged by foreign substance or iron pieces.

This machine is divided into two types; The standard type and the short head type. Normally the large size of material is fed into the standard type, which means that the size of discharge is also much coarse; And the small size of material is fed into the short head type due to its steep crushing cone. Which will unavoidably influence the size of discharge, and therefore it is much suitable for producing the fine goods. Consequentially the standard type is generally used for medium and coarse material, and the short head type for medium and fine material.

Cone crushe Operating principle:
Cone crusher is made up of frame, transmission device, hollow eccentric shaft, bowl-shaped bearing, crushing cone, springs and hydraulic pressure station. When cone crusher works, the motor drives the eccentric shaft shell to turn around through a horizontal axle and a pair of bevel gears. The shaft of crushing cone swings with the force of eccentric shaft shell. While the swaying, the crushing wall's surface will approach and separate with the roll mortar wall again and again. Therefore, the stones will be crushed.
