Materials are impacted and crushed through hammers driven by the rotating rotor of the machine. Then the impacted materials are compressed, sheared and grinded between the ring hammer and the crushing plate.

The feeding materials are firstly impacted between the quick revolving rotor and hammer driven by the spindle, then crushed again while being bumped against the board.

The machine with different type of tooth to satisfy different customers, is mainly used to crush low-hardness materials such as coal, coke and others.

PCF type crusher is mainly used in cement industry to crush materials with compressive strength less than 200Mpa like lime, gypsum, coal, marl, shale etc. The characteristic of the machine is uniform grain size, simple structure, high workability

PF type impact crusher is welcome in construction industries as highway construction, water-development project, airport project, and so on, to perform mid-crushing of minerals and rocks with compressive strength of no more than 320 Mpa following the coarse crushing of jaw-crushers.

FPGB-Graded crusher with low speed, high torque drive system. Using special type cavity and tooth shape change of traditional double toothed roll crusher, collision and squeezing material shear and tensile force of natural texture of crack damage
