ABSTRACT:
A separator disc for use in a disc separator for separating a mixture of grain and/or grain-like particles according to particle length. The disc separator, of conventional construction, is characterized by a series of spaced parallel discs, mounted for rotation on a common shaft. The discs are partially submerged in the mixture. Pockets in the exposed plane surfaces of the discs lift shorter grains from the mixture and dump them as the discs rotate, to thereby separate the particles. The separator disc is formed of a castable polyurethane material and is radially split to provide for removal from the shaft and replacement of individual discs in a direction transverse to the axis of the shaft.
