ABSTRACT:
A hopper-feeder system for feeding stored powders at a uniform, controllable and predetermined rate. A spiral convoluted stirring agitator in close proximity and conforming to the hopper wall is rotated in a direction tending to lift and dilate the powder, counteracting its tendency to bridge and to undergo intermittent or non-uniform changes in density and rate of discharge. The head load upon the feeder as well as the material damping effect on the feeder are controlled by a column cutter on the agitator that undercuts the column of powder extending through the hopper opening.
