  • Woodwaste processing system with contaminate separation
    Patent number: 5915565
    Abstract: A system for processing wastewood. The system may be mounted on a towable chassis. The wastewood is received at one end of the system and metal contaminants are removed from the wastewood. The wastewood is then separated according to size wherein a first size of wastewood is further processed by the system and a second size is removed from the system for subsequent re-processing. Unwanted paper and plastic contaminants are removed from the wastewood, and the wastewood of the first size is subjected to a further separating step wherein it is again separated according to size into usable end products.
