Four Shaft Shredders

Four Shaft shear type shredders have a perforated screen attached, which determines the product size exiting the shredder. The second two sets of cutters on the side shafts return any product unable to fit through the perforations in the screen back to the cutting chamber for reshredding. Product exiting a four shaft shredder is determined by the cutter width and the holes (perforations) in the screen. Four shaft shredders are fed vertically.
