In a single-stage classification system using an almost rigidly rotating flow in which very small feed-powder particles suspended in a liquid medium (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, with the aim of raising throughput by increasing concentration of feed suspension, we have made dense-slurry classification-experiments in order to pursue suitable classification-conditions in high-concentration processes. Consequently, we have reached the following conclusions. (1) In a large-particle classification both higher feed-ratio at the initial water-feed for a dense classification than that for a dilute one and resetting the feed-ratio of slurry to that of water just before classification allow an accurate dense classification with the same cut size as that for a dilute one. (2) In a small-particle classification, the difference in classification conditions causes little difference in classification performance.
