ABSTRACT:
A fabricated sheet metal housing is positioned above a hopper and has inlets for receiving conduits which conduct air carrying small scrap pieces of paper or other material. The housing encloses a perforated cylindrical drum supported for rotation on a horizontal axis, and rotary seals extend between the housing and opposite end portions of the drum and between the drum and a stationary air outlet manifold at one end of the drum. Air flows inwardly through the rotating drum and deposits the pieces on the outer surface of the drum, and a stationary air jet tube within the drum directs a high velocity air stream outwardly and downwardly through the perforated drum for transferring the particles from the drum downwardly into the hopper. A set of motor driven blowers supply the air and pieces of material to the housing and also suck the clean air from the outlet and blow the air through filter bags. Another blower supplies air to the stationary jet tube within the drum.
