This series of two-shaft shredder features low noise, low energy consumption and high output. It reflects the superiority of low speed and large torque cutting design. This series of shredders is particularly suitable for the crushing of large-sized plastic materials. After being shredded, the bulk density of the material can be increased, thereby reducing transportation costs. In addition, the material can be further processed after shredding, such as material separation, washing and pelletizing etc.
