SCC-15-B screen classifying cutter

The SCC-15-B screen classifying cutter reduces hard, soft, and fibrous materials into particles of controlled sizes at high rates and with minimal fines. The proprietary rotor, consisting of cutter heads attached to interconnected parallelograms (a helical array of staggered holders), continuously shears oversize materials against twin, stationary bed knives. The cutter tips, which are available in stainless steel, tool steel, and tungsten carbide, can be slid onto blade holders and secured with one retaining socket-head screw, which allows for rapid replacement. The SCC-15-B cutter has carbide-tipped cutter heads along its entire shaft, with no frontal gaps between the tips. As a result, material is cut into uniform pieces with minimum imperfections or fines, and little to no generation of heat. The cutter has a 15-in.-wide (381 mm) throat that accommodates up to 30 parallelograms with 60 cutter inserts. Bed screen perforations range from 1/32 in. to 1.5 in. (0.79–38 mm) in diameter and up to 3 in. (76 mm) square, allowing the reduction of materials into uniform particles as small as 20–30 mesh. Shaft rotation speed is infinitely variable between 30 and 3,600 rpm. The cutter system is suitable for food, chemical, mineral, and plastics products.
