One of the most versatile types of shredders is the twin shaft industrial shredder , such as the Goyum shredder. These shredder machine employ two parallel counter rotating stacks of cutters that intermesh at low speed below extremely high torque. As the cam shaped cutters intermesh at close clearance, they cut, shear, tear, slice, and rip apart a range of materials into smaller items generally in a strip or chip-like output shape. The geometry of this twin shaft cutter also makes it very good at feeding in irregular shaped solids. This kind of industrial shredder generally employs no size screen that the output particle is determined by the cutter shape. Twin shaft industrial shredders is also designed for specific solids like tires, medical waste, documents, bottles, municipal solid waste and more. The specifics of the application determine the configuration of the unit although some shredders have a specific style for only one application and are not versatile by any means. In
