A new Magnum Model 72 Screen Classifying Cutter from Munson Machinery (Utica, NY) reduces infeed products spanning a wider range of sizes, at approximately 75 percent higher rates than standard size models of equivalent length. The cutter features: 

  • An 18” (457 mm) overall diameter rotor.
  • A 72” (1,829 mm) long helical array of 72 interconnected four-sided stars, which hold 288 carbide cutter tips that continuously shear oversize materials against twin, stationary bed knives. 
  • No frontal gaps between the cutter tips, so material is cut into uniform pieces with minimum imperfections or fines, and little to no heat.
  • Bed screen perforations that range from .125” to 4” (3.18 to 102 mm) diameter, allowing the reduction of materials into uniform particles in sizes down to 6 mesh.
  • An infeed throat measuring 72” x 22.5” (1,829 x 572 mm) that accommodates a range of material types and sizes to be recycled or otherwise reduced in size for processing. 
  • Applicability for wood, fiberglass, cardboard, friable plastics, gypsum, rigid foam, and numerous other uses.
  • Material fed through the top of an adjustable, double-baffled intake chute, or directly into the front of the chute through a hinged door.
  • An independently powered, variable speed pinch roller for horizontal feeding of material.
  • Discharge via gravity, pneumatic collection, or independently powered belt or screw conveyor.
  • Cutter tips, secured with one retaining socket-head screw for rapid replacement, supplied as standard in tungsten carbide — various grades of hardened stainless steel available.
  • Lengths down to 24” (610 mm) and configured with multiple V-belt drives as standard, or optional direct-coupled gear-reduced drives.
  • Availability in carbon steel, abrasion-resistant steel and stainless steel.
