An installation for transporting fine-grained material to a consumer using two alternately filled and emptied pneumatic pressure vessels (3, 4) together with an outlet valve (12, 12') and a control nozzle (15, 15') in the material discharge pipe of each of the two pressure vessels. The control nozzles (15, 15') are connected to an air distributor (18) through which the control nozzle receives a reduced amount of compressed air when the material discharge pipe is shut off. With an installation such as this, a continuous and exactly metered delivery of fine-grained material is obtained without any mechanically moved parts in the delivery path and with a low rate of flow in the delivery pipe.

Installation for transporting fine-grained material

A method of performing a treatment of a dust cloud includes the successive steps of generating the dust cloud from a gas and from solid particles, passing the dust cloud through a reaction zone, separating the dust cloud into its components in a separator, and reintroducing at least one part of at least one component into the dust cloud. There is further formed a solids column into which fresh or recirculated solid particles are introduced. The solids column which seals the gas used for generating the dust cloud from the separator, is height-adjustable for controlling the concentration of solids in the dust cloud formed from the solid particles constituting the solids column.
