Knelson™ Gravity Concentrator – for maximising gold …

High gold recovery with fully fluidised cones. Our concentrator’s leading-edge cone technology has been built on 40 years of innovation and is designed to capture the maximum amount of gold per cycle. Knelson is the only enhanced gravity concentrator with a fully fluidised bed allowing for upgrading throughout the entire cone surface.

Research and application of a Knelson concentrator: A ...

15-06-2020· The original concentrator is a single-walled rotating concentrator, but the recovery capabilities begin to down-grade in seconds because the voids are quickly filled by particles. On solving this problem by injecting water into the bowl under pressure to counteract the centrifugal force and create fluidization, the first KC was manufactured ( Knelson, 1992 ).
