This Munson Model SCC-15-SS Screen Classifying Cutter with a double-width infeed hopper accommodates conveyor-feeding of irregular shapes and sizes of hard, soft and/or fibrous materials by gravity.
The 30 in. (76 cm) wide hopper funnels materials into a 15 in. (38 cm) wide throat positioned over a solid-mass rotor containing staggered parallelograms, each of which holds two, half-inch (12.7 mm) wide cutter tips that are easy to replace using one machine screw.
As material enters the infeed chute, it is subjected to successive mechanical shearing against bed knives until small enough to pass through bedscreen apertures, resulting in uniform size reduction from coarse down to 20 mesh with minimal fines or heat generation, at high rates with reduced energy use.
Bedscreen perforations range from 1/32 to 2 in. (0.79 to 51 mm) in diameter and up to 3 in. (76 mm) square. The shaft rotates at 30 - 3600 RPM, producing up to 500 cu ft/h (14 m3/h) of sized product, depending on application.
