Abstract

Pneumatic conveying plant for loose material, comprises at least one storage bin (7) for loose material, a respective pneumatic conveying line (8) for feeding material from the or each storage bin to a weighing bin (1) through a line (9) under the action of a suction device (3) which provides for coarse metering of the material. A respective intermediate bin (4) is connected into the or each conveying line to receive material for fine metering to the weighing bin (1) through lines (5) by means of a static overpressure. This overpressure can be produced, for example by a gravity feed or by a mechanical discharge device such as a screw conveyor. <IMAGE>
