Abstract
A transport plug for pneumatically transporting solid materials in a transport pipe by the use of a pressurized transport gas and a pneumatic transport method of solid materials employing the transport plug. The transport plug comprises two bodies consisting of a front body and a rear body defining a material storing space for storing solid materials between the two bodies, at least one supplementary body connected to the rear body, and flexible connecting means coupling said three bodies. A supplementary material storing space is defined between the supplementary body and the rear body. Solid materials are fed into the material storing space of the transport plug, transported through the transport pipe together with the transport plug, and received in a collector under gravitational fall.
