The shredder is mainly used for crushing materials. A twin-shaft shredder (also known as a shear type shredder) is one of shredders that mainly reduces the size of materials by shearing, tearing, and squeezing, and is widely used for crushing waste plastics, waste rubber, wood, and other large-volume wastes. The double-shaft shredder bites the material into a crushing area by utilizing the friction force of the roller surface, cuts, extrudes and tears the material, and the material bears the extrusion or splitting to achieve the purpose of crushing. To increase the cleaving action, teeth or grooves are often made in the roll surface.
