Principle

When pyfb pyfd compound cone crusher working, by the motor through V-belt, host pulley, drive shaft, a small bevel gear, bevel gear driving a large external brass rotation axis line of cone crushing force copper out by rotating the mantle next move, making the broken wall near the surface from time to time and mortar wall from time to time to leave the rolling surface, so that the material in the fixed cone and fixed cone crushing cavity composed of the ring constantly under attack, pressing and bending and breaking. After repeated squeezing, shock and bending, the material crushing to the required size, the lower discharge.

Features

1. Even granularity of the crushed product reduces 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.
2. The big type machine adopts hydraulic safe system. The spring safety system is the protection unit against overload, and keeps the crushing chamber from being damaged by foreign cubstance or iron pieces.

Benefits

Big power, high efficiency, high handling capacity, low operation cost, easy adjustment, economical operation and longer running performance.

Fields

PYFB PYFD Compound Cone Crusher is widely used in metal and non-metallic mines, cement, construction, sand and metallurgical industries. It is applicable to materials all kinds of ores and rocks with hardness of medium or above, like iron ore, nonferrous metal ores, granite, limestone, quartzite, sandstone, pebbles and so on.
