First, when the transport pipe is blocked, the work of disassembling the transport pipe, removing the blockage, and restoring the pipe are required, but in order to do this, the transport must be stopped once,
Moreover, since it takes a long time to recover, continuous transportation is not possible. In addition, since the distributor 7 is provided in the middle of the transfer route, the flow may change there, resulting in the retention of the powder or granular material, which in turn may cause the transfer pipe to be blocked. Further, in the distributor 7, it is difficult to perform quantitative distribution because the distribution ratio changes due to external factors such as the supply destination pressure and the transfer pipe pressure loss.
