Abstract
A disc pelletizer wherein the inner sides and an adjacent annular portion of the bottom of the pan are covered with ultra high molecular weight polyethylene or the like. The uncovered bottom portion of the pan is cleaned by vertical rods having tungsten carbide tipped bottoms, which rods are carried by an arm which is rotatable about a circular path corresponding to a radius of the bottom of the pan, so that as the pan slowly rotates, sucessive circular paths are described by the tungsten carbide tipped bottoms to effectively clean the bottom of the pan with minimum expenditure of electrical energy.
