The frame is a rigid structure with openings at the top and bottom, used to support the eccentric shaft and withstand the reaction force of crushed materials, requiring strength and stiffness, generally made of cast steel through integral casting.
The hammer crusher has a compact structure, reasonable layout, convenient installation, good maintainability, and is easy to operate. It has good adaptability to the layout of cement production processes, saving process layout space; it features a large crushing ratio for materials.
Hammer crushers are divided into ordinary hammer crushers and ring hammer crushers. Ring hammers are generally used more widely in industries such as coal and coke crushing. Ordinary hammer machines are usually indicated by the English prefix PC, while those indicated by the prefix PCH are generally ring hammer crushers.
The main working component of the hammer crusher is the rotor equipped with hammers (also known as hammer heads). The rotor consists of a main shaft, a disc, a pin shaft, and hammers. The motor drives the rotor to rotate in the crushing chamber. Materials are fed into the machine from the upper feed port and are crushed by the impact, shock, shear, and grinding action of high-speed moving hammers. A screen plate is installed at the lower part of the rotor; during crushing, particles smaller than the screen hole size pass through and are discharged out of the machine, while larger particles remain on the screen plate to continue being impacted and ground by hammers before being discharged outside through the screen plate.
