In a single-stage classification system using an almost rigidly rotating flow in which very small feed-powder particles suspended in water are accurately classified into fine and coarse products by the difference in centrifugal force and fluid drag acting on each particle due to the particle-size difference, we conducted classification experiments, with the aim of raising throughput by increasing flow rate and feed-concentration for a constant centrifugal-effect parameter. Consequently, we have reached the following conclusions. (1) The cut size scarcely change for a high flow-rate and feed concentration. (2) Increasing flow-rate for a dilute feed-concentration improves classification accuracy while that for a dense feed-concentration decreases accuracy. (3) Increasing feed-concentration for a low flow-rate improves classification accuracy while that for a high flow-rate decreases accuracy.
