ABSTRACT:
An inflatable liner for mounting within a hopper type receptacle or container which receives and discharges flowable bulk particulate material. The liner is comprised of one or more inflatable members such as inflatable fabric bags or tubular members loosely supported by sling members at spaced locations along the interior surface of the walls of the container in such manner that each inflatable member is capable of limited miltidirectional movement with respect to the adjacent container wall and a flexible wear resistant cover sheet loosely covering the wall and the inflatable members. The slings may be attached to either the container wall or to the bottom side of the cover sheet. Alternate inflatable members are inflated and deflated in any desired sequence to cause the cover sheet to undulate and thereby set up a continuous cyclic wave motion which serves to maintain the continuous flow of particulate material through the container.
