Product Description
Product DescriptionGold concentrator machine working principle:Gold centrifugal concentrator is a fairly new kind of gravity concentration apparatus. It is a machine that uses the principles of a centrifuge to boost the gravitational force which is experienced by feed particles so as to enable separation on the basis of particle density. A concentrate bowl that has a cone shape, which rotates at a high speed and powered by an electric motor with a pressurized jacket that encompasses the bowl are the key components of this unit. Near the centre of the bowl from above, feed material that comes from the cyclone underflow or the ball mill discharge is fed as slurry towards it. The slurry that is fed contacts the vessel’s base plate and as a result of the rotation, it is thrust outward. The concentrate bowl has some outer extremities which houses a series of ribs which has a groove between each pair of the ribs. The lighter material rises upwards over the grooves during operation and the heavy mineral particle (that usually has economic value) is trapped in them. Along the perimeter of each groove, pressurized water is injected through a series of tangential water inlets so as to maintain a fluidized bed of particles to allow heavy mineral particles to be efficiently concentrated in it.Nelson gold centrifugal concentrator technical parameters:ModelSTLB20STLB30STLB60STLB80STLB100Feeding capacity(t/h)0-0.62-38-1235-4570-80Fluidization water required(m3/h)2-33-57-1030-3655-80Slurry Water Required(m3/h)1.5-45-78-1235-5070-120Feeding Density(%)0-500-500-500-500-50Feeding size(mm)0-30-30-50-50-5Concentration Cleaning Up CycleVein gold 1-3 Hours Placer gold 2-6 HoursConcentrate weight(kg)210-2030-4060-7080-90Power (KW)0.751.541122Approximate shipping weight(Kg)145400100015002000Approximate shipping dimensions (mm)790x785x7901180x1140x12501970x1670x17502300x1800x22002400x2000x2300Application 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 a particle size of 0.004mm, it is up to 97%.Main Features of Gold Centrifugal Concentrator:1) High recovery rate: Through our test, the recovery rate for placer gold can be 99% 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 tailing 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.
