Abstract

A disc screen includes a shaft, a first disc mounted on the shaft, and a second disc mounted on the shaft. An interfacial opening (IFO) extends between the first disc and the second disc. A width of the IFO as measured between the first disc and the second disc varies according to a rotational position of the shaft.
