Falcon VS Knelson Concentrator. Centrifugal concentrators widely used in metal mines at home and abroad generally have horizontal and vertical types. The disadvantage of both types of centrifugal concentrators is that they can only produce intermittently, which reduces the efficiency of mineral processing.

"The combination of the RG100 with the Knelson MD12 concentrator is an excellent match. Even the most stubborn clays are disintegrated by the autogenous scrubbing action in the drum section (assuming correct feed rate), and this plant combo is excellent for processing of eluvial and alluvial ores, especially smaller high value deposits.
