---About product

   Centrifugal Concentrator was patented in China. It is an efficient equipment for recovering free gold in all particle  size ranges,specially for recovery of fine gold which is lost during the operation of the gravitational concentrators (sluice boxes and jigs). It can be used not only for placer gold mining, but also for hard rock mining to recover the  natural gold, replacing amalgamation, and recover gold from the old tailings.

---Application
The feed slurry contacts the base plate of the vessel and, due to its rotation, is thrust outward. The outer extremities of the concentrated bowl house a series of ribs, and between each pair of ribs is a groove. During operation the lighter material flows upward over the grooves and the heavy mineral particles (usually of economic value) becomes trapped within them. Pressurized water is injected through a series of tangential water inlets along the perimeter of each groove to maintain a fluidized bed of particles in which heavy mineral particles can be efficiently concentrated. The Knelson concentrator typically operates as a batch process, with lighter [gangue] material being continuously discharged via overflow and a heavy mineral concentrate periodically removed by flushing the bowl with water.

---Main features
