This classifying cutter has a proprietary rotor design

The Model SCC-15-SS Screen Classifying Cutter is a high-torque, low-speed unit that reduces hard materials and friable products into controlled particle sizes. Its proprietary rotor design features cutter bits that are attached to a helical array of staggered holders called “interconnected parallelograms.” These parallelograms continuously cut and crush oversize materials against twin stationary bed knives. Unlike high-shear cutters that rotate at high speeds, the high-torque cutter is equipped with a direct-coupled, gear-reduced drive that rotates the shaft at speeds down to 10 rpm to cut and crush tough materials using low shear, and to minimize the production of fines when cutting friable materials. The cutter bits, which are available in stainless steel, tool steel and tungsten carbide, can be slid onto holders and secured with one retaining socket-head screw, allowing rapid replacement. The SCC-15-SS positions the bits along the entire shaft, with no frontal gaps, reducing materials into uniform pieces with minimum imperfections or fines, and with little or no generation of heat. — Munson Machinery Co., Utica, N.Y.
