Knelson Concentrator
The Knelson Concentrator relies on an enhanced gravitational force together with fluidization process to recover even very micron sized particles. First water is injected into the rotating concentrating cone through series of fluidization holes. Then feed slurry is introduced through a stationary feed tube. Once the slurry is filled in each cone, create a concentrating bed and high specific ...

Gold Recovery with Centrifugal Gravity Concentrator
Here is how a gravity gold concentrator (centrifuge) works as a separator: Make sure the concentrator has been correctly assembled and that all bolts have been tightened. If required, attach a funnel to the material feed inlet. If necessary, connect a hose to the tailings outlet. Place the concentrator on a raised structure such as blocks. Place a receptacle under the barrel to collect the ...
The potential for dry processing using a Knelson Concentrator
May 01, 2013 · Highlights 3″ Knelson Concentrator has been configured to operate under dry conditions. Synthetic ore of tungsten and silica was used to mimic a gold ore.
