Abstract
A powder body metering apparatus for metering a powder body such as a synthetic resin raw material is structured such that a powder body outlet of a metering container of another metering apparatus is connected to a second opening (50), whereby a powder body transport system is constructed, the powder body within the metering container of the other metering apparatus can be transported to a predetermined place via a metering container (32), by finishing a discharge of the powder body within the metering container (32), thereafter keeping a switch valve (36) in a closed state, filling the powder body in the metering container of the other metering apparatus and thereafter generating a gas stream toward a first opening (49) from the second opening (50), thus the metering container (32) being utilized as a part of a transport pipe.
