ABSTRACT:
An aggregate separator has a fan-shaped separating surface made up of an array of diverging end-stretched wires which are permitted to oscillate individually in response to vibratory stimulus. The surface includes a plurality of identical fan-shaped panels, each panel including a plurality of wires and a pair of end sheaths which retain the ends of the wires in fixed relation to each other so that the wires of each panel diverge. Each panel is stretched on the frame of the separator until the length and tension of the wires are substantially the same. Intermediate transverse bridges may be used to position the wires between the upstream and downstream ends of the separator and ensure that the effective spacing between adjacent oscillating wires does not exceed the exit interval.
