Abstract: The invention relates to the feeding of finely divided particulate matter in a fluidized state from a source to a plurality of discharge points wherein discrete quantities of particulate matter are discharged by suitable feeding devices. In more detail, the invention comprises a primary air activated gravity conveyor and a plurality of secondary air activated gravity conveyors leading away from the primary conveyor to direct particulate matter to the feeding units associated with each secondary conveyor. The primary and secondary conveyors are maintained full of fluidized particulate matter at all times.
