Operating Principle:

The main working part of hammer crusher is rotors with hammer. The rotors consist of main shaft, disk, pin shaft and hammers. The motor drives the rotors to rotate quickly in the crushing cavity. Raw materials enter the crusher through the feed opening and are stricken, impacted, cut and ground by the high-speed hammer to small size. There is a screening plate under the rotor, so that materials with size smaller than the screen mesh will be screened out and others are left to be further hammered and ground until reach the standard size. The size of the final product can be adjusted by changing the screening plate. The gap between the rotors and the screening plate can also be adjusted according to different requirement.

Working principle:

PCH hammer crusher manufactured by Shanghai Shibang Machinery Co., Ltd. is a kind of rotor impact crusher containing ring hammer. Its main component is the rotor containing hammer (also called hammerhead).The rotor is composed of main shaft, disk, pin and hammer. It is driven by motor to rotate rapidly in the crushing cavity. The materials are delivered through upper feed inlet into the equipment, and crushed by knocking, impact, shearing and grinding by the quickly moving hammer. The crushed materials with grain size smaller than the mesh opening will be discharged through screen plate on the lower part of the rotor, while those with grain size larger than the mesh are left on the screen plate to undergo impact and grinding by the hammer, and finally discharged through the screen plate.
