PURPOSE:To control the flow rate of a powder and particulate body by controlling the amt. of feed by providing a weir, etc. to the bottom part of a transporting pipe, increasing the density of the downflow of the powder and particulate body which is fluidized in the transporting pipe, and supplying gas to the midway of the transporting pipe. CONSTITUTION:In a process for transporting a powder and particulate body P in a transporting pipe 6 in the fluidized state of P as it is fluidized in a closed tank 1, the P is flowed downward by the gravity by extending the transporting pipe 6 almost vertically; and a bent pipe, horizontal pipe, inclined pipe, stationary reduced pipe, and a weir, etc. are provided to the bottom part of the transporting pipe 6 to increase the density of the downflow of P. Further, gas is fed from gas feeding pipes 8-10 to the midway of the transporting pipe 6, and the flow rate of P is controlled by controlling the amt. of the feed of the gas. In this way, the flow rate of the downflow of P of high density is controlled.
