Grizzly Mill

Known as the heavyweight champion of the wood waste industry, the CBI Grizzly Mill is the backbone of our biomass recovery systems. It is recognized worldwide as the toughest and most productive wood hog ever built. With multiple rotor types and sizes available, it can be configured specifically as a primary, secondary or tertiary grinder for waste wood (stumps, logs, demolition debris, MSW, telephone poles and railroad ties, stringy bark, yard waste, etc.) for end-product sizes ranging from 15mm–500mm.

    The superior design of our solid steel rotors (available with optional brute package) allows it to turn at half the speed of a conventional hammer-mill’s rotor, saving up to 90 percent of maintenance costs. The rotational speed is fast enough to make a highly uniform end product but slow enough to make the Grizzly Mill extremely tolerant to rock and metal contamination. All rotors are locked to the high strength alloy shaft by two B-Loc locking assemblies.
