<p>A method for dense phase pneumatic conveying of particulate material comprises pressurising a feed vessel (10) and commencing flow of gas to a transport line (15). Valve (14) in the solids discharge (13) of feed vessel (10) is opened and the solids flow through solids discharge (13), through feed line (15) and into receiving vessel (16). Receving vessel (16) has all outlet ports therefrom closed during conveying such that the pneumatic conveying system comprises a closed end system. The step of conveying the solids occurs in the transient phase, rather than in a continuous phase common to prior art systems. In a preferred method, the solids are received by a primary receiving vessel and overflow gas and solids from the primary receiving vessel flow into a closed and secondary receiving vessel.</p> |
