Abstract

1. Apparatus for the continuous delivery of accurately measured quantities of fine material from a storage bin (1) or production arrangement to a consuming arrangement in which at least two pneumatic pressure vessels (3, 4) which are alternately filled and emptied are provided between the storage bin or production arrangement and the consuming arrangement and an outlet valve (12, 12') which can be shut off and an adjustable valve which affects the material flow are arranged in each material discharge pipe (14), characterized in that a) the adjustable valves in the material discharge pipes (e.g. 14) are constructed as control nozzles (15, 15') which affect the material flow pneumatically and are arranged behind the outlet valves (12, 12') - viewed in the direction of movement of the material - and in that b) the control nozzles (15, 15') are connected to an air distributor (18) by means of which a quantity of control air can be supplied corresponding to the selected quantity of material conveyed when the material discharge pipe (14) of the relevant pressure vessel (e.g. 3) is open and a reduced quantity of control air can be supplied when the material discharge pipe of the relevant pressure vessel is closed.
