<p>A storage container (1) for solid particulate materials (2) includes a source of "lubrication" gas (A) coupled to a fluidiser (4). The fluidised particulate materials are carried from the container by a stream of transport gas (B). A deflector (6) placed over the container outlet (7) constrains the fluid flow in a substantially horizontal path to prevent the outlet becoming blocked by the solids when the gas flow (B)-(A) is cut off. The proportions of particulate material can be varied by selectively varying the pressure in the container, where the container (1) is a pressure vessel.</p> |
