Hammer Crusher Machine is a commonly used crushing equipment. Mining Machine has a large crushing ratio (generally 10-25, and the highest is 50), high production capacity, uniform products, less excessive powder, low energy consumption per unit product, simple structure, and equipment Light weight, easy to operate and maintain. The main working part of the hammer crusher is the rotor with a hammer (also called hammer head). The rotor consists of a main shaft, a disc, a pin and a hammer. The motor drives the rotor to rotate at high speed in the crushing chamber. The material is fed into the machine from the upper feeding port and is crushed by the blow, impact, shearing and grinding action of the high-speed moving hammer. In the lower part of the rotor, there is a sieve plate. The particles smaller than the screen hole size in the crushed materials are discharged through the sieve plate. The coarse particles larger than the screen hole size are retained on the sieve plate and continue t…
