Abstract
Powders with a relatively low bulk density can be emptied from transportation containers only with a large and undesired production of dust. The apparatus for emptying powder-filled containers consists of a suction tube on which a fluidizing device is arranged in the neighborhood of the open end of the tube. This fluidizing device can have the form of a double-jacketed cone concentrically about the tube, or a hollow sphere concentrically about the tube. Fluidizing air can be introduced into the powder through bores arranged in the direction of the opening of the tube. To prevent the suction tube being sucked onto the container wall, the opening of the suction tube has a crenelated edge.
