Abstract
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.
