ABSTRACT:
A rotary disc screen composed of a bed of rotary discs in spaced relation and formed in the periphery with undulating surfaces for constantly agitating the waste material to be screened, and having a controllable drive system for the rotary discs subject to control sensor which is sensitive to the distribution of the waste material along the length of the rotary screen for adjusting the speed of the discs making up the rotary screen to control the residence time of waste material and maximizing the screening efficiency so that certain classes of components in the waste material are given an opportunity to fall through the spaces between the discs for collection and transport to a separate area from the remainder of the waste material that is moved through the full length of the rotary disc screen.
