Shredders with sizing screens are suitable for applications requiring high output with precise fraction sizing. The waste which falls into the hopper is shredded and then falls freely (by gravitation) onto the rotating drum screen. The pieces of the crushed material of the guaranteed size fall through the screen holes. The waste which does not fall through the screen is carried by the drum blades back into the hopper and then it walls back into the shredding area. The process is repeated until all crushed material parts have the guaranteed size and fall through the screen. The sizing screen is designed for shredder types SDS 560, SDS 850 and SDS 1000 but after a minor adjustment it can also be used with SDTx 4 and SDTx 4L shredders. The screen surface of the sizing screen can be replaced by a new one or different mesh size. For operation, the screen surface is covered for safety and for cleanliness around the device. The total output of the machine depends on the mesh size, which can be 15, 20, 25–40 mm.

 The final inclined conveyor carries the crushed material into the next processing stage or into a container.
