Cutter Housing and Rotor Design
Laboratory Mini Cutters are constructed of heavy-duty weldments to form a solid assembly. Smaller M-2 and M-3 models have an integral motor mounted cutter assembly. Larger M-6 and M-12 models have externally mounted, large diameter, flanged block bearings to support the rotor shaft. The rotor consists of positive rake, tungsten carbide cutters for extreme life. The cutters are progressively stacked to form a solid helical mass.
Standard cutters are designed with a baffled hopper. Munson can supply units with infeed conveyors, pinch-roll feeders, "mailbox" style feed chutes or transitions as required by the application.
Drive and Mounting
The smaller M-2 and M-3 models have a unitized assembly mounted on a C-faced motor. On the larger M-6 and M-12 models, the cutter and motor are mounted on a common base which can be configured for either pneumatic or gravity discharge. Cutter speeds range from 100-3500 RPM depending on application. Standard drives are direct or V belt. Optional gear drives can be designed for reduced speed and high torque. Drive guards are included.
