Rotary Knife Cutter Provides Controlled End-Product Sizes
June 14, 2010
The new rotary knife cutter delivers controlled end product sizes with minimum fines at ultra-high rates. Intended as a cutter/cracker for corn and other grains, spices, roots and related food products, the unit is equipped with a machined, one-piece rotor assembly containing five, adjustable, rotating knives that cut against four, reversible, screen-mounted stationary knives. All cutting surfaces are of hardened tool steel. The cutter rotates at 550 RPM as standard, or at other speeds to suit special applications, propelling on-size particles through a perforated screen having apertures from 1/16- to ¾-inch allowing tight control over desired end-product sizes. Material discharges through a flanged outlet by gravity or pneumatically. The screen provides 270 degrees of exposure and is retained within dual, hinged housings with machined channels that allow easy access and rapid screen changes. The unit is equipped with guards enclosing the V-belt drive assembly, and sealed flange block ball bearing assemblies supporting the rotor assembly in a heavy gauge steel housing, providing vibration-free operation. Optional feed hoppers are available with baffles and a slide gate to control flow for conveyor feeding. The cutter offers hinged doors on both sides of the unit for rapid cleaning and inspection, and is available in carbon steel or all-stainless construction.
