Abstract
An apparatus for separating materials into different sized particles, especially difficult materials that may contain wet or sticky particles or lightweight foreign material. The material is separated by feeding it into a dish-shaped unit open at the top with screen material along its sides and bottom. The unit is rotated about an inclined axis so that the open top faces upwardly and toward the front. The material to be separated is placed into the unit, and the unit is rotated so that the material rolls on itself across the bottom and up the sides with the smaller particles moving downwardly where they pass through the screened sides and bottom as the unit rotates over a conveyor. The larger particles exit through the open top of the unit. The apparatus also includes a unique way of providing for the screen medium.
