Use simple actions such as hammer impact and striking to complete the crushing of non-metallic materials. After the equipment is powered on, the power is transmitted to the rotor by a high-speed and high torque electric motor, and the rotor starts to run at high speed. The hammer head on the rotor is used to crush the metal material entering the crushing chamber. The hammer head and the lining plate cooperate with each other to form a crushing space. The waste metal material is crushed into qualified finished particles after being impacted, torn, impacted, and polished in the crushing space.
