ABSTRACT:
A pneumatic conveying system has a compressor of known capacity connected to a compressed air storage tank having a plurality of valve output lines which if all open at the same time would reduce the air pressure available to each line below a required amount. Hoppers are provided for supplying to said lines, material to be conveyed and a control is provided for selectively opening and closing the valves and ensuring that not more than a certain air volume demand is placed on the storage tank by a number of lines in operation at the same time. Each conveying line contains a restriction adapted to maintain substantially constant mass flow rate of air therein leaving the storage tank.
