a high-efficiency and low energy consumption crusher, specially designed for films, small hollow bottles and PET bottles. According to the characteristics of different materials, the crusher is equipped with a variety of rotor models for choosing. The diameter of the rotor ranges from 500mm to 800mm. The minimum width of the rotor is 700mm and the maximum is 1600mm. A targeted rotor structure can be designed to achieve the best crushing effect. It adopts a special welding process for the overall steel structure to meet the demand for the materials which are not easily broken. Large rotor bearings, tool holders and rotors are combined with standard V-shaped cutting technology, which is beneficial to improve cutting and recycling efficiency and reduce the dust content in recycled materials.
