<p>A rotary cylinder type separator comprises a slightly tiltable, horizontally installed rotary cylinder, a plurality of combs secured to the inside of the cylinder, in parallel and substantially axially of the cylinder, a feeder for introducing a mixture of grainy material and impurities into the cylinder at one end, an outlet formed at the other end of the cylinder for discharging the grainy material out of the cylinder, and a device for discharging the impurities larger in size than the grainy material and that have been scooped by the combs to a high level and have then fallen within the cylinder. The last-mentioned device is a fan for producing an air blast within the cylinder, or a combination of a stationary collection trough inserted axially through the cylinder for receiving the impurities that fall from the high level, and a screw conveyor mounted inside the trough.</p> |
