A self-clearing rotary screening system (300, 300′, 300″, 300′″) includes a frame (110) having a longitudinally extending axis (112). The frame (110) includes a plurality of longitudinally extending frame members (114) disposed in angularly spaced relationship, one with respect to another, about the axis (112). The system (300, 300′, 300″, 300′″) includes a plurality of screening members (116) fixed between respective pairs of the plurality of frame members (114) to define a longitudinally extending cavity (118). A drive system (120) is coupled to the frame (110) for rotating the frame (110) about the axis (112). The system (300, 300′, 300″, 300′″) includes a plurality of displaceable members (210, 210′, 310, 410) pivotally coupled to respective portions of the frame (110). The displaceable members (210, 210′, 310, 410) are displaced responsive to rotation of the frame (110) about the axis (112).
