[0002] Hammer mills are mainly composed of a body, rotor, guide plate, screen pressing mechanism, and screen plates. The body forms the crushing chamber and supports the rotor. The rotor consists of a main shaft, hammer frame plate, hammers, and pins. The motor drives the rotor to rotate at high speed through a coupling. The material is crushed by the impact of the high-speed rotating hammers. The guide plate causes the material to enter the crushing chamber tangentially, and the screen plates ensure that the crushed material meets the expected requirements.

[0003] Material enters through the feed inlet and is tangentially guided into the crushing chamber by the guide plate. It is crushed by the impact of the high-speed rotating hammers. The material rebounds and impacts the screen. Qualified material passes through the screen holes, while unqualified material is crushed by the friction of the screen. The crushing process is repeated continuously.
