Unit eases shredding of bulky containers

The Weima Group has developed a new version of the WLK 12 single-shaft shredder for size reduction of bulky plastic containers and parts with thin-gauge wall thicknesses, such as totes, barrels, drums, and tanks. The compact design of the machine includes a new press-down device that enables the customer to shred even the largest size totes without the need to pre-cut.This new single-shaft shredder is equipped with a ’doghouse’ design hopper that is open over the rotor. Whole pieces are directly loaded into the front of the machine. After the container is loaded into the cutting chamber, the integrated press-down device ensures that a part is situated in the bottom of the shredder. A horizontal ram pushes the material into the rotor parallel to the down stroke of the press-down device.Both pressing actions are controlled by electronic controls that ’read’ the amp-load on the main motor and optimize the pressure applied to the cutting rotor. This optimization acts to keep material in constant contact with the rotor. When material is shredded small enough it will pass through a screen that is mounted under the rotor. At this point, the material can be further granulated if desired.The working width of the WLK 12 is 1,200 mm (47.2 inches). This size machine can handle intermediate bulk containers and other large totes along with materials in sizes up to 1 by 1 by 1m. Throughput is 600-1000 kg/hr (1300-2200 lb/hr) with screen sizes from 20-100mm (3/4-4 inch). Alternative sized machines are available upon request.
