Abstract
An improved method and the related system for pneumatically transporting a powder or granular material placed in an airtight storage container through a transport pipe in high density. In the invention, pressurized gas is being intermittently supplied to the airtight storage container containing the material therein so as to take out of the container and a transport plug is being synchronously fed into the base of the transport pipe, whereby the powder or granular material is successively formed into a long column inside the transport pipe and is pneumatically transported at very slow speed.
