A high density pneumatic transport system of solid materials from an airtight transport tank through a transport pipe into a collector. In the airtight transport tank materials are successively fed into a charge tank by reciprocating a slide damper. Simultaneously materials stored in the charge tank are successively pushed out into the transport pipe by supplying pressurized gas intermittently and transported continuously at high density through a lower horizontal pipe and a vertical riser pipe, then transported in the form of a long column in an upper horizontal pipe at a very low speed by deceleration by a divergent means, and finally collected into a storage tank of the collector.

High density pneumatic transport system for use with solid materials

A method and the related system for sampling solid materials. Materials as continuously manufactured from a compression molding machine are sampled at fixed intervals and the materials thus sampled are fed into a transport pipe so as to be transferred by being accompanied by a transport plug into an inspecting station at low speed from its stand-by position in the pipe when a gas control means is set in a feed mode. After transferring sampled materials the transport plug left at its terminal position in the transport pipe is automatically returned to the stand-by position through the transport pipe when the gas control means is set in a suction mode. By executing the above steps repeatedly, sampled materials are successively transferred into the inspecting station by being accompanied by the transport plug under unmanned operation.
