The main working part of a hammer crusher is the rotor with hammers (also called hammer heads). The rotor consists of a main shaft, a disc, a pin and a hammer.' The rotor is driven by an electric motor and rotates in the crushing chamber. The material is fed into the machine from the upper feeding port and is crushed by the striking, impacting, shearing and grinding action of the moving hammers. In the lower part of the rotor, there is a sieve plate, the granular grade of the crushed material which is smaller than the size of the sieve is discharged through the sieve plate, and the coarse granular grade which is larger than the size of the sieve is stopped on the sieve plate and continues to be struck and ground by the hammers, and is discharged from the machine through the sieve plate.Large feed size ,short crushing time High product rate, high material uniformity.Simple operation, low energy consumption, few operators Easy to operate, easy to move.Alloy steel is used for the easily damaged parts The strength is greatly increased Long service life.
