ABSTRACT:
A modular screening apparatus has four parallel shafts arranged in a single plane mounted to each module. The shafts extend between the sides of the machine frame and are driven by a motor and timing belts which connect the shafts directly or indirectly to the drive motor. Each shaft supports three beater bars which are equally spaced about the axis of the shaft. A screen bed defined by a perforated polyurethane plastic sheet overlies the plane containing the driven shafts. The sheet serves as a screen which is clamped at its upstream edge, the downstream end extending over a fixed bar and vertically downwardly, to suspend a weight. The sides of the screen abut adjustable side plates which are mounted to the machine frame and define the boundaries of the screen bed. The beater bars rotate on the shafts to strike the underside of the screen.
