ABSTRACT:
A weight is attached to a conically shaped hollow member which rests on the top of a bed of particulate material in a tube, with the weight functioning to prevent fluidization of the material in the tube. The conical member is provided with elongated slots whereby fluid exiting from the bed flows into the interior of the hollow member, through the slots and into the tube outlet.
