<p>PURPOSE:To provide a method, worth which low running cost and cost of equipment and small installation area are realized, for separating mud and sand from a synthetic resin piece adhered with mud or sand in order to reclaim the synthetic resin. CONSTITUTION:In a polishing machine, in which a rotatable roller 3 is provided in a rotatable drum 2 under the condition that the center line 22 of the rotating shaft of the drum is parallel and, at the same time, offset to that 32 of the rotating shaft of the roller, synthetic resin pieces 6 adhered with mud or sand is charged in the clearance part between the drum 2 and the roller 3 so as to rub with each other through rotations of the drum 2 and of the roller 3 in order to polish and cut the surface of each synthetic resin piece 6, resulting in separating mud or sand from the synthetic resin piece.</p> |
