MSW size reduction is carried out by large machinery, which utilizes force to smash, break, shear or cut the material into smaller and potentially more uniform particles. There are two prominent categories of waste comminution devices used in the management of MSW: high-speed,low-torque(HSLT)hammermill shreddersand low-speed,high-torque(LSHT) shear cutters.
