ABSTRACT OF THE DISCLOSURE Pneumatically-conveyable particulate material is withdrawn from a hopper using vacuum wands extending into the interior of the hopper. The wands are operated in a cyclic sequence, with material being withdrawn from each wand in turn. This permits material to be withdrawn substantially continuously where the material tends to compact together in flow-preventing bridges and the invention can be put into practice employing a relatively simply applied attachment connected on the exterior of the hopper.
