Abstract:
1. A self-clearing rotary screening system, comprising: a frame having a longitudinally extending axis, said frame including a plurality longitudinally extending frame members disposed in angularly spaced relationship, one with respect to the others, about said axis; a plurality of first screening members coupled to said plurality of frame members, each of said plurality of first screening members being affixed between respective pairs of said plurality of frame members to define a continuous envelope of said first screening members surrounding a longitudinally extended cavity open on opposing ends; a drive system coupled to said frame for rotating said frame about said axis; a plurality of second screening members disposed within said longitudinally extended cavity and hingedly coupled to respective ones of said plurality of frame members between adjacent pairs of said first screening members, said second screening members being pivotally displaced from a first position screening a material through openings therein to at least a second position shedding residual material into said cavity responsive to rotation of said frame about said axis.
