- The experimental results on wet classification of ultra-fine calcium carbonate below 8 μm using an industrial scale disc-stack nozzle centrifuge system are presented. The parameters such as G-force, disc geometry, nozzle size, split, feed rate have been analysed by a statistical approach. The results show that the centrifuge is capable to efficiently classify the micron-sized material at 40% in mass. The product size distribution becomes finer and steeper after removing the undesired coarser particles from the feed. In addition, the centrifugal classification performance is empirically correlated to the parameters used.
