ABSTRACT:
Apparatus for emptying a drum of powdered material. The drum is mounted on a support at a 45.degree. angle to vertical. The drum has a cap having two holes and sleeves projecting into the drum from the holes. The sleeves are aligned with the bottom corner of the drum. A feed tube, loosely surrounded by a guide tube, is inserted through each of the sleeves into contact with the powder in the drum. Each feed tube has a vacuum pump which aspirates powder through the tube and out of the drum while atmospheric air passes between the feed and guide tubes to fluidize the powder. A vibrator is mounted on the support for the drum to continually vibrate the powder toward the lower ends of the feed tubes.
