A chipper shredder is an industrial shredder that processes a material into small chips. Chipper shredders can be used to process a variety of materials including waste rubber, used tires, wood, plastic and computer parts. Chipper shredders are useful in waste disposal and reprocessing operations because they allow for materials to be resized uniformly in advance of the next stage of processing.

Uses for Chipper Shredders
Chipper shredders are versatile waste resizing and disposal utilities. In tire recycling and disposal, for example, large, irregularly shaped tire pieces can be difficult to process. Tire chips of uniform length are more easily handled by secondary processing equipment and therefore more effectively processed. Chippers are valuable for the same reason in the processing of other materials. A chipper shredder’s attributes in a given setting depend on the scale of a given disposal or reprocessing operation and the kind of material being processed. Permanent recycling stations, for example, may make use of one large, permanent chipper shredder system in tandem with additional baling, shredding and other processing equipment. For companies that provide processing services on a contract basis, a smaller, portable chipper that can be mounted on a trailer is more practical. Such portable chippers are often used in mobile tire shredding operations.
Design of Chipper Shredders
A chipper shredder, like many other kinds of industrial shredders, is usually equipped with a feeding shaft into which waste materials are loaded. At the bottom of the shaft, two or more rollers layered with jagged teeth rotate toward each other, squeezing, tearing, and slicing the waste materials enough that they pass between the rollers in segments. In the case of chipper shredders, the teeth and rollers are configured so that the emerging pieces conform to a specific shape. Assorted factors like torque, horsepower, roller size, roller speed and many other factors will depend on the variety of waste material being processed. Beyond the chipping phase of processing, there are many possible destinations for the newly processed materials. In the case of wood chipping, the chips can be sent for cleaning in advance of sale to consumer or commercial gardening suppliers. For tire processing or disposal, the tire chips are sometimes sent directly to a landfill, or they can be placed in a screening system to remove any tire chips that were not shaped correctly during the chipping process. Every chipped material has the potential to continue to additional processes, including other chipping machines, until the material achieves the appropriate shape for processing or disposal.
