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.
