ABSTRACT:
This invention relates to a comminuting device which processes small pieces of bulk materials, such as pieces of rubber tires, into crumb-sized particles. It is designed to operate at slow speeds, 50-350 rpm by having the work material move along the exterior peripheral surface of a rotating drum cutting efficiencies are improved. This unique invention provides cutting teeth on the stator and drum each having limited rotational movement which permits greater efficiency for cutting multi-grade materials such as rubber tires having steel and material cord. Cutting blades can be rotated three times to expose unused cutting edges before replacement is required.
