High Recovery Ratioe,Automatic,Factory Direct Knelson Gold Centrifugl Concentrator
Introduction
Gold
concentrator is a new type of gravity concentration equipment for concentrating gold,silver,tin,lead. centrifugal gold
concentrator successfully separates the minerals under the high speed centrifugal rotation of the bowl as well as pressured
fluidization water. centrifugal gold concentrator 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.
Application
Gold centrifugal concentrator can be used not only for placer gold mining, but also for hard rock mining to recover the natural
gold, replacing amalgamation. Knelson gold concentrator is also used to recover gold from the old tailings.
A).Hard Rock Mining: (No Chemicals Required) - NO Mercury, NO Cyanide
B).Alluvial / Placer Deposit Mining & Dredging
Primary gold processing when you know your gold is too fine for a sluice
Reprocessing years of old fine mineral concentrates
Processing daily sluice box fine mineral concentrates
C).Enriching/Upgrading Fine Mineral Concentrates
Classifying and upgrading sluice concentrates
Upgrading concentrates for regional processing
D). Prospecting / Drilling / Bulk Sampling
Features
1. High concentrating ratio and high recovery
2. Total process automation, steady recovery performance
4. Environmentally friendly(requires no chemical additives or reagents)
5. Low water and electricity requirements
6. Low production costs, durable wear parts, minimal maintenance requirements
7. Compact design requiring less space, easy merged into the existing mining processing
8. Quick payback on investment, typically lass than half year
9. Rugged design and a high degree of quality manufacturing ensures that every Concentrator will provide many years of reliable,
trouble-free operation in even the most severe operating environments.
Working Principle
The double-layer centrifugal bucket is divided into two layers, inner and outer. The inner layer is a vertebral body like a
washing machine, which is made of stainless steel and has an annular spacer. The inner vertebral body has many small holes and the outer layer is also cone-shaped. Form a closed water jacket with the inner layer. The middle transmission shaft is a hollow shaft, and the pressurized water is punched into the inner sleeve of the double-layered centrifugal barrel through the hollow shaft, and is sprayed into the partition between the small holes of the inner layer to form a back flushing water. The selected gold-bearing minerals enter the bottom of the double-layer centrifugal bucket in the form of slurry from the upper feeding tube. Under the action of high-speed centrifugal force, the slurry slides upward along the inner cone, and heavy material such as heavy monomer is precipitated between the spacers. The light substance slides up until it reaches the upper mouth of the double-layered centrifugal barrel and is discharged through the tailings trough. The heavy substance between the strips is under the impact of the recoil,
and the heavier substance is deposited on the bottom layer of the spacer, the lighter substance It is constantly replaced by new heavy materials into the compartments. After a period of time, the gold-containing heavy substances between the compartments are removed. That is to complete a beneficiation process.
