These screeners are self-contained production screening machines for separating dry materials according to particle size. Screener models can have from one to five screen surfaces, for separations with openings from ½-in. to 325 mesh. The gyratory-reciprocating motion begins with a horizontal circular motion at the feed end that immediately spreads the material across the full width of the screen, maximizing screen use. The circular motion gradually diminishes along the length of the machine to an elliptical path, and finally to a nearly straight line motion at the discharge end. This motion allows the machine to process material at a high-capacity and improves screening performance with near-size material. There is no vertical component to this motion, thus keeping the material in constant contact with the screen surface.
