The cone crusher of PYFB series, widely used in the industries of metallurgy, building material, road construction, chemical engineering & silicate,is suitable for crushing all kinds of ores abd rocks with hardness of medium or above. This cone crushing machine features the high crushing ratio, high efficiecncy,high handling capacity, low operation cost, easy adjustment and economical operation.The quality of material used for components and reasonable design of construction contribues 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 ferrly,because of the wide range of products to be provided.



This cone crusher machine adopts grease sealing so as to prevent the watering and draining systen 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.
