The high-torque, low-speed model SCC-15-SS Screen Classifying Cutter reduces hard materials and friable products into controlled particle sizes. A proprietary rotor design is comprised of cutter bits attached to a helical array of staggered holders called "interconnected parallelograms" that continuously cut and crush oversize materials against twin, stationary bed knives. The unit is equipped with a direct-coupled, gear-reduced drive that rotates the shaft at speeds down to 10 RPM to cut or crush tough materials using low shear and to minimize 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 unit has a 15-in. (381-mm) throat width that accommodates up to 30 parallelograms with 60 bit inserts.
