High efficiency gold knelson centrifugal concentrator
Gold Knelson concentrator is the equipment use gravity method to collect gold concentrate,
mainly used in the gold mining and other pricious metal recovery industry. it mainly adopts the gravity method to collect the free
gold powder or particles from the placer gold or the ball mill
ground materials. It’s an ideal gravity method equipment to replace amalgamating,
mercury and cynide chemical. It is widely popular in small miners
or big volume gold mining site.
Working principle
Knelson gold centrifugal concentrator is also called centrifugal gold collector, mainly to collect free
gold particles in the vein gold ore or alluvial placer gold rock.
It’s an good gravity alternative equipment to replace amalgamating,
mercury and cynide chemical. It uses the eccentric gravity power to
collect the free gold concentrate in the inner cone groove. The
final application results prove that the recovery rate can be as
high as 80%, especially for the free gold in the alluvial gold in
the placer gold ore. The recovery rate for the gold ore slurry of
0. 074mm out of the ball mill can also reach more than 70%.
Product pictures
1. Centrifugal concentrator is more effective for the treatment of
micro slime, and the recovery rate for grain fractions of 37 to 19
micron is as high as about 90%, because the separation of mineral
grains in a centrifugal concentrator is based on the combined
effect of centrifugal force and lateral flow membrane. , so the
total enrichment ratio is higher than the plane gravity chute;
2. Centrifugal concentrator uses the effect of centrifugal force, thus
strengthening the re-election process and shortening the sorting
time. Therefore, the processing capacity is large, about 10 times
that of the automatic chute;
3.small footprint, high degree of automation.
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.
