A new Model SCC-15 Screen Classifying Cutter cuts hard, soft or fibrous materials into controlled particle sizes with minimal fines at high rates, according to this firm. The cutter features a patented helical rotor design with dozens of cutter heads attached to a helical array of staggered holders called "interconnected parallelograms" to continuously shear oversize materials against twin, stationary bed knives. Primarily employed for coarse grinding of materials into particles of uniform sizes ranging from granules down to 20 – 30 mesh, the cutter has a 15 in. throat width and can be fitted with 30 parallelograms with 60 cutter inserts. Bed screen perforations range from 1/32 to 1-1/2-in. in diameter and up to 3 in. 2, according to material characteristics and desired particle size. The shaft rotates at 30 to 3600 rpm, producing up to 500 ft 3 /h of sized product, depending on the application. — Munson Machinery Company, Inc., Utica, N.Y.
