Ways of improving pneumatic transport throughput

Comparative equipment indices are given for transporting cement. An operating principle is proposed for a chamber feeder without aeration devices, i.e. with use of an injector for compressed air supply from openings directed at the bottom of the reception chamber. Material movement is demonstrated over an inclined plane with charging of a chamber feeder. Injector channel length, the dependence of channel length on its inclination and width of the sprayer channel slot, are determined.
