Abstract

A separation screen has multiple discs configured to receive a material stream at an in-feed end and move a first group of materials from the material stream up an inclined angle and over a top out-feed end of the separation screen while a second group of materials from the material steam either fall through openings between the discs while being carried up the separation screen or roll off the in-feed end of the separation screen. A heating system heats an outside surface of the discs so that the discs can separate the first group of materials from the material stream during cold environmental temperatures.
