AUTOMATIC CONTROL DEVICE FOR THE FLUIDIZATION OF BULK MATERIAL

摘要

Automatic control device for the fluidization of bulk material comprising an air pressure sensor (3) mounted above the level of the bulk material in a reservoir (1) and a sensor (2) sensing the compactness of the bulk material mounted below the level of the bulk material in the reservoir (1) both sensors being connected to an air pressure controller (4) which is connected, through an "OR," logical circuit (6), to a valve (9) for instant discharge of the air pressure in the reservoir (1) and to a compressed air source (8).
