ABSTRACT:
Apparatus for separating urban waste materials is formed with a vertically extending duct having a waste material inlet and a suction device at the upper end of said duct with a slanted wall being provided opposite the material inlet to deflect downwardly into the duct certain portions of the waste material caused to impinge against the slanted wall. The duct inlet is formed to enable ambient air to enter the duct through the interstice of the inlet in order to impart an accelerating force to the incoming material.
