Abstract

1. Method of pneumatic discharge of fine-grained material from a storage container (1) into a pressurised feed pipe (2) in which the material in the storage container is under a regulable pneumatic pressure and passes out of the storage container through a regulable pneumatic nozzle (5) into the feed pipe and the pneumatic nozzle and the pneumatic container pressure are regulated as a function of the desired quantity of material discharged, characterised in that a) the quantity of material discharged is continuously determined by weighing of the container, b) in the event of deviation of the quantity of material discharged from the predetermined theoretical value the pneumatic nozzle is regulated so as to keep the quantity of material discharged constant, c) and when the limits of the range of regulation of the pneumatic nozzle are reached, the pneumatic pressure in the container is also regulated in such a way that the pneumatic nozzle remains within its range of regulation.
