The revolution characteristic of feed rate of a rotary feeder is examined theoretically and experimentally when back pressure is not applied to the feeder outlet. The revolution giving the maximum feed rate is dependent on the inlet dimension, the total volume of wheel rooms and the number of wheel rooms of the feeder and on the relaxation time of solid particle. For solids having large relaxation time the maximum feed rate becomes independent of the relaxation time. Discrepancy between experimental results and a theory is largely due to irregular outflow of solids from a hopper to the feeder inlets.
