ABSTRACT:
A method of distributing powdered or granular material to a plurality of feeding ends in a system having a pressurizing tank for pressurizing and fluidizing a powdered or granular material, a plurality of transportation pipes having one ends constituting discharge nozzles opening above a fluidized bed in the tank and the other ends connected to different feeding ends so as to introduce the material to the feeding ends, and a plurality of booster gas supply pipes for supplying respective transportation pipes with a booster gas. The internal pressure of the tank is controlled by a controller provided with a set valve in accordance with the mean value of the terminal pressures at the feeding ends, the mean value of predetermined set flow rates of the booster gas in the booster gas supplying pipes, and the mean value of predetermined set rates of transportation of material to the feeding ends.
