Abstract
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.
