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.
