Product Desciption
1.Product Description of centrifugal concentrator
Gold Concentration Separator is kind centrifugal concentration equipment. It can be used not only for placer gold mining,
but also for hard rock mining to recover the natural gold, replacing amalgamation. It is also used to recover gold from the old tailings.
Since 1985, three models of Gold Concentration Separator have been developed. Application shows that the recovery can be as high
as 99%, especially for the case in recovering the natural gold in lode ore with 65% of the ore having a milling size of-0.074mm, the
recovery for the natural gold is expected up to 98%. For that natural gold of 0.004mm in particle size, the recovery is 97%.
The cleaning up cycle is 1~4 hours. And the upgrade ratio is up to 1,000 times.
2.Working principle
Centrifugal gold concentrator is a relatively new type of gravity concentration apparatus. The machines utilise the principles
of a centrifuge to enhance the gravitational force experienced by feed particles to effect separation based on particle density.
The key components of the unit are a cone shaped "concentrate" bowl, rotated at high speed by an electric motor and a
pressurized water jacket encompassing the bowl. Feed material, typically from a ball mill discharge or cyclone underflow bleed,
is fed as a slurry toward the centre of the bowl from above. The feed slurry contacts the base plate of the vessel and due to its rotation,
is thrust outward. The outer extremities of the concentrate bowl house a series of ribs and between each pair of ribs is a groove.
During operation the lighter material flows upward over the grooves and heavy mineral particles (usually of economic value) become
trapped within them. Pressurized water is injected through a series of tangential water inlets along the perimeter of each groove to
maintain a fluidized bed of particles in which heavy mineral particles can be efficiently concentrated.
4.Main Features
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 tailing and water. Low noise, no chemical agent involved.
