Abstract
The center piece of a particle feeder for steady feeding of fine particles at low rates has been modified by sweeping the particles upward into a concentric tube which also serves as the piston support. The new design has demonstrated superior short and long term stabilities of particle feeding rate; moreover, it has significantly extended the operating ranges of the carrier-gas flow rate, particle feeding rate, and particle size and type.
