The KC is essentially a vertical axis bowl-type centrifugal concentrator that uses a fluidized bed to concentrate the dense material over a wide size range (0.02–0.850 mm), which is composed of a feed and discharge system, separation system, power system, and water supply system (Koppalkar, 2009).The concentrate bowl is the core component of a KC, and its …
In Zimbabwe, a 20-year-old Knelson was replaced by a competitor machine on the promise of better support from the competitor. Within three years, the mine purchased and installed a new FL Knelson instead. ... The first Knelson Concentrator was trialled in 1976, 40 years ago, and Knelsons have been at the forefront of the industry ever ...

The particle classification in the enhanced gravity field generated by the Knelson concentrator was studied in this paper. Three main test parameters, namely rotation speed, backwash water pressure, and solid mass percentage, that affected the classification performance of the Knelson concentrator for the classification tests of quartz and synthetic ore, which …
The Knelson Concentrator is a compact centrifugal separator with an active fluidized bed to concentrate high SG minerals (Knelson, 1992; Knelson and Jones, 1994). It was initially developed for gold processing, which commonly employed semi-batch units, as the yield to the concentrate was typically below 1 %. However, due to its relatively low ...
