Product Description

High efficiency gold knelson centrifugal concentrator

 

The automatic Discharge Centrifugal Gold Concentrator is also call Knelson gold centrifugal concentrator, or gold centrifuge. It is mainly used to collect the free gold particles from the placer alluvial gold sand or rein gold slurry ground by the grinding mill, like ball mill or wet pan mill.
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 0.074 mm ,the recovery is expected up to 98%.For 0.004 mm size natural gold, the recovery is 97%.

Working principle

The raw material containing gold sand and water is fed into the concentrator, and the concentrator bowl is rotating with the the powder of the motor. The raw material is spalshed back and forth by the eccentric power from the bowl liner. Meanwhile the backlash water will be washing the raw material from the bottom of the bowl liner. Because of the gravity eccentric power, the heavy gold concentrate will be keeped and stay in the groove of the bowl liner, and the light sand will be discharged from the discharge mouth.

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.
