The MUNSON® CX Heavy Duty Cutter is a high-torque cutter/hog that delivers a positive raking action for reducing blocks and chunks of high-density materials up to 30 in. (762 mm) wide and 8 in. (203 mm) high, into particles ≥ 1/16 in. (1.6 mm) depending on application.
The rotor assembly is comprised of tightly stacked discs that are interlocked to rotate as one high-inertia mass. Each disc is machined with two full-width slots on opposing sides that are fitted with replaceable tool steel cutter inserts of the same width, with no gaps between cutter pathways, subjecting the entire face of incoming material to aggressive ripping action.
The solid rotor discs act as a backstop for incoming materials to control particle size and limit the feed rate to prevent overcharging of the chamber.
In addition to shredding the material, the cutters shear it against a full-width, tight-tolerance bed knife located at the downswing side of the material chamber.
The high-mass rotor is driven by an oversized sheave and V-belt drive at 300 RPM as standard, producing the high torque and inertia needed to tear through products that would stall or overload standard cutters. Also offered are gear reduced
drives and other arrangements allowing variable rotor speeds from 150 to 900 RPM to optimize performance for specific applications.
