The gas operated particle feed apparatus may feed particles to an outlet port. There may be a fixed member having a bottom with a particle aperture centrally disposed therein, an annular wall upstanding from the bottom and a plurality of gas apertures. The fixed member may be attached to a base member that may have a central outlet port. A particle outlet element with a constriction aperture may be disposed between the fixed member and the base member. A rotating member with a disk, an agitator, a feed aperture, and a radial disk groove with a ball therein may be disposed in the fixed member and restrained transversally by the wall. Groove apertures may be formed in the disk. A top member may be disposed on the fixed member and may have a central opening. The agitator may protrude through the central opening.
