ABSTRACT:
A system for unloading powdered or granular materials from a container made of flexible material, the system including a line supplying compressed gas to the interior of the container to fluidize the material in the container, and a delivery conduit which may be attached to the container for delivering fluidized material from the container. A pair of arms are movable between a first position in which they are spaced from the container and a second position in which they engage and squeeze the container. Vibrators are provided for vibrating the container. The action of the arms and the vibrators facilitates unloading by breaking up clumps of the material in the container and preventing the formation of air pockets and material bridging.
