This paper proposes new high-throughput classifiers of FOF-CB and FOF-MCM types for an accurate wet centrifugal classification of low mass concentration slurry. The new classifications make use of an almost rigidly rotating through-flow that is formed by only the feed suspension. The classification performance of both types has been studied by numerical simulations of fluid and particle motions, and the classifiers have proved to be effective. The FOF-CB type classifier is able to attain high-throughput batch-type classification by partitioning the collection region of a fine product into two regions. The FOF-MCM type classifier, on the other hand, can be a high-throughput continuous-type classifier by extracting coarse and medium products continuously from the housing and by separating the collection region of a fine product into two regions. However, the medium product does not become the classified product because it includes both fine and medium fractions.
