Knelson Gold Centrifugal Gravity Concentrator Separator
MachineWater jacket type centrifuge concentrator is also called
Nelson centrifuge concentrator, which is widely used for the
selecting and recovery of sand gold and rock gold. It's an ideal
equipment for inland river gold mining and rock goldMining.Now we
have five models. Application shows that the recovery can be as
high as 99%, especially for recovering the natural gold from ore
with the grinding size of 65% ore is 0. 074mm, and the recovery
rate of natural gold is as high as 98%.For the natural gold of
0.004mm in size, the recovery rate is 97%. The cleaning cycle is
1~4 hours for rock gold, and 4-8 hours for placer gold. The
enrichment ratio is up to 1,000 times.Structure And Working
Principle:The motor of the device drives shaft by belt, which makes
the separating cone spin at high speed. The ore pulp is fedeto the
separating cone through the feedingtube, and the pulp is
strengthened by the centrifugal force field. The heavy mineral
keeps in the groove of the separating cone, and the light mineral
is discharged through the tails chute. After the machine stops, the
concentrate is discharged from the outlet.Centrifugal

Feature 1.
High recovery rate: Through our test, the recovery
rate for placer gold can be 98% or more, for rock gold, the
recovery rate could reach 97% when the feeding size is below
7mm.2. Easy to install: Only a small leveled
place required. It's a full line machine, before starting it, we
only need to connect the water pump and
power.3. Easy to adjust: There are only 2
factors that will affect the recovery result, they are water
pressure and feeding size. By giving proper water pressure and
feeding size, you could get the best recovery
effect.4. No pollution: This machine only consumes
water and electric power, and exhaust tailings and water. Low
noise, no chemical agent
involved.5. Easy to operate: After
finishing the water pressure and feeding size adjust, clients only
need to recover the concentrates every 2-4 hours. (Depending on the
