The WL 6s shredder is used for shredding large quantities of wood and timber waste. The machines are fitted with very high powered rotors of 800 mm width. The rotor diameter is 368 mm. The large rotor and the wrap angle of the screen ensure high throughput rates. Machines with a drive output of 30 kW or more are fitted with a hydrodynamic clutch, in additional to the automatic star-delta starter, to ensure a soft start of the rotor even when the hopper is completely full. Material is fed through the hopper to fall in front of a hydraulically operated drawer pressing the material, according to load, onto the turning rotor. The material is shredded between the rotor knives and a fixed stationary counter knife. The drawer is equipped with castellation as is the floor to prevent materials being lodged between the drawer and the machine casing. The chips produced can be conveyed from the output of the machine by an air extraction system, screw or belt conveyor.
