It is mainly composed of organic shell, bearing, screen, transmission wheel and trough frame. All materials are cast from manganese steel. The wood shredder is composed of a body, a middle body and a lower body. The middle body is equipped with a triple stator ring, a crushing cutter and a fineness analyzer. The main machine adopts alloy cutter head. It has a high degree of wear resistance, which also improves production. The rotor of the crusher is driven by the motor to run at a high speed, so that the high-speed airflow generated by the machine produces high-strength impact force, compression force, and cutting force on the crushed material, and achieves a unique crushing function.
