Abstract
This paper proposes a new triple-product classifier named FOF-MCWCM for a wet-type high-throughput centrifugal classification of a low particle-concentration slurry using an almost rigidly rotating flow produced between rigidly rotating housing and core walls (O and W represent feed and water supply; F, M and C represent fine, medium and coarse products). The classification performance has been investigated by numerical simulations of fluid and particle motions and it is proven to be effective. This type is developed by dividing a collection part for C in our previous double-product FOF-CWC into two collection parts for M and C. A fine product F in the previous FOF-CWC is unchanged in this type, while a coarse product C in the former is divided into medium and coarse products, M and C, in the latter. The FOF-MCWCM successfully classifies the feed into three products (F, M and C).
