Abstract
An apparatus for distributing powdered particles from a single pressurized transporting vessel to a plurality of receiving ends through a plurality of transporting pipes. The vessel is supplied with a pressurized gas to fluidize the powdered particles, which then are distributed to the transporting pipes which include discharge control valves to control the discharging rate of the particles in each of the transporting pipes. The transporting pipes are supplied with booster gas, the flow rate of which is controlled by a booster flow rate control valve. The booster flow rate control valve in each pipe is controlled in cascade by a booster flow rate controller receiving an output signal from a differential pressure detector for detecting a differential pressure of a discharging nozzle at the end of the pipes. Since the discharging rate of the powdered particles is in proportion to the differential pressure, the discharging rate can be controlled at a desired rate by the booster flow rate controller in accordance with the differential pressure of the discharging nozzle.
