Abstract: Powdered free-flowing material is simultaneously withdrawn from each of a set of adjacent parallel hoppers by a widening pipe contg. a barrier member and directly entering a common pneumatic feed conduit. The conduits have adjacent by-pass conduits which through spaced connectors deliver compressed air to the feed conduits to move the material at relatively low speed. Non-return valves in the connectors present counter-flow. Delivery of compressed air is dependent on one or more control monometers which respond to pressure in the feed conduits or to presence of solids in conduits or their feed pipes.
