ABSTRACT:
Screening apparatus for fractionating material suspensions has a screen gap which is defined by a rotatable member and a stationary member. One of these members is provided with at least one projection which extends into the screen gap to inhibit clogging of the gap with coarse suspension materials. Any coarse suspension materials stuck in the screen gap can be removed from the screen gap by a wiper element extending from the rotatable member and overlapping the screen gap.
