China Knelson Fully Continuous Type Centrifuge Gold Concentrator/Centrifugal Concentrator/Gold Concentrator

What is Knelson Concentrator??

The Knelson concentrator utilizes the principles of [centrifuge] to enhance the gravitational force experienced by feed particles, which aids in the separation process based on particle density. The key components of the unit include: a cone shaped "concentrate" bowl, which is rotated at high speed by an electric motor and a pressurized water jacket encompasses the bowl. Feed material, typically from a ball mill discharge or cyclone underflow bleed, is fed as a slurry toward the center of the bowl from above. 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.

For now, five models have been developed. Capacities range from laboratory scale to 150 tons of solids per hour.Beneficiation test shows that the recovery can be 99%,especially for recovering the natural lode ore gold,when 65% Grind size are smaller than 0.074mm,the recovery is expected up to 98%.For 0.004mm size natural gold, the recovery is 97%.

The cleaning up cycle is 1~4 hours. And the upgrade ratio is up to 1,000 times.

If the water pump is connected to the control box, the feeding water,back wash water, machine start and stop, and the concentrates discharging can all be controlled automatically by the control box. gold centrifuge|gold concentrator|centrifugal dewatering machine|china
