High recovery rate gold knelson centrifugal concentrator
The Gold Centrifugal Concentrator is a brilliant gravity separation equipment widely used in the mining industry, especially for the placer gold, fine grain rock gold, and other precious minerals.
【Modes】(1) Timed automatic discharge centrifuge, customizable, higher efficiency, higher price.
(2) Non-automatic discharge centrifuge, common use, in stock, manually stop working and take out the gold concentrate after few hours of operation. We have it both in industry type and laboratory type small centrifuge.
(3) Customized fixed centrifugal concentrator and mobile concentrator (mobile gold wash plant usually equipped with portable trommel screen, portable gold centrifuge, portable gold shaker table, etc).
【Brand】 Knelson Concentrator,Ascend gold concentrator is the best replacement for Knelson Concentrator with affordable price, complete models, wide capacity range.

Feeding: slurry pump or gravity flow by the height difference
After gold centrifuge: tailing ⇒ sluice box; concentrate ⇒ shaker table or amalgamator
【Gold Concentrator VS Jig Concentrator】 Centrifugal gold concentrator is easier debugging, and gold safer. It only can take out the gold concentrate after 4-6 hours of continuous work.
Working principle
The rotor of the centrifuge rotates at a high speed. Under the action of centrifugal force, heavy minerals are stacking on the inner plate groove of the rotor cone, and the light ore particles are gradually discharged. After about 4-6 hours of operation, stop feeding, and turn on the backwater to wash out the gold concentrate.
Gold centrifugal concentrator is useful in the gold recovery in all ranges of particle size. It is most especially useful for recovering fine gold which gets lost during the operation of gravity concentrators. The application has shown that the recovery of gold can be very high, as much as 99% and the concentration ratio is up to 1,000 times. In the recovery of natural gold in lode ore that has a particle size of -0.074mm, the gold recovered is about 98%, for recovery of gold in particle size of 0.004mm, it is up to 97%.
Product pictures
(1) Gold centrifugal concentrator has a high recovery and high concentrating ratio. (2)Center discharge design that enables fast and secure concentrate removal. (3) Eco-friendly ( needs no reagents or chemical additives). (4) Low energy, low water consumption. (5) Durable wear parts with easy maintenance. (6) Fast returns on investment, usually less than 6 months.
The gold centrifugal concentrator used in combination with the vibrating chute, gold shaker table, gold wash plant and other gold extraction equipment to increase the fine gold recovery rate.
Customer working site
The centrifugal usually works together with the gold grinding mills like ball mill, wet pan mill or chillean mill to be fed with gold ore slurry and select the free gold or big size gold, the remaining gold will be discharged and goes to the shaking table or gold sluice so that the tailing gold can be reselected.
