Abstract
An improved method and related system for pneumatically transporting powdered or granular materials stored in an airtight storage container to a collector through a transport pipe in the form of a lengthy column in high density and at a slow speed by the use of pressurized gas. The method of the invention comprises the steps of stopping feeding of the pressurized gas when the whole of the powdered or granular materials corresponding to a final batch contained in the storage container are sent into the material transport pipe, simultaneously discharging the internal pressure of the storage container through a gas decompressing means, inserting a transport plug from the base end of the material transport pipe, and carrying forward the transport plug at a slow speed by feeding pressurized gas from the base end of the transport pipe.
