Cutter Transforms Hard, Soft and Fibrous Materials into Controlled Particle Sizes
Munson Machinery's Model SCC-15 Screen Classifying Cutter cuts hard, soft and fibrous materials into controlled particle sizes with minimal fines at high rates. The cutter features a 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.
The cutter tips are available in stainless steel, tool steel and tungsten carbide and can be slid onto blade holders and secured with one retaining socket-head screw for rapid replacement.
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-inch (381-millimeter) throat width and can be fitted with 30 parallelograms with 60 cutter inserts. Bed screen perforations range from 1/32 to 1.5 inches (0.79 to 38 millimeters) in diameter and up to 3 inches (76 millimeters) square, according to material characteristics and desired particle size. The shaft rotates at 30 to 3600 rpm, producing up to 500 cu ft/h (14 cu m/h) of sized product, depending on application.
Material is fed through the top of an adjustable, double-baffled intake chute or directly into the front of the chute though a hinged door. An independently powered, variable-speed pinch roll feeder is offered for horizontal-rolled product feed. The unit is equipped with a multiple V-belt drive motor and is available with a direct-coupled gear-reduced drive.
