The double-shaft shredder cuts and tears materials into smaller sizes through the shearing and tearing action of the blades during their relative rotation, which facilitates subsequent processing or achieves the purpose of volume reduction. Thanks to its structural form and low-speed rotation, the dual-shaft shredder is characterized by high torque, strong shearing force, high processing capacity, good stability, and low noise. Therefore, it is widely used in the field of solid waste treatment and can meet the recycling and reuse processing needs of various types of solid waste.
