ABSTRACT:
Accurate metering and dispensing of small quantities of abrasive material comprised of particles or powder, or both is accomplished by feed apparatus comprising a rotatable tubular member having a threaded interior surface for transporting the abrasive material through the tubular member in response to rotation of the member about the axis thereof. The discharge portion of the tube is particularly adapted to dispense frequent, small quantities of the material rather than less frequent larger quantities.
