ABSTRACT:
A shale shaker has been developed which, in one aspect, has one or more upper screens and one or more lower screens with an upper screen at a discharge end of the shale shaker and a lower screen disposed to receive material discharged from a discharge end of one of the upper screens. In one aspect a portion of a lower screen underlies the discharge end of the upper screen. In another aspect a solid flowback pan prevents material falling through the upper screen(s) from falling onto the lower screen(s); and, in another aspect, the pan prevents material on a top of the lower screen(s) from falling into a bottom sump of the shale shaker which receives material which has fallen through the screen(s).
