Considerations in Belt Feeder Design & Operation

As its name implies, a volumetric feeder modulates and controls the volumetric rate of discharge from a bin (e.g., cu. ft./hr.). The four most common types of such feeders are screw, belt, rotary valve, and vibrating pan. A gravimetric feeder, on the other hand, modulates the mass flow rate. This can be done either on a continuous basis (the ...
