Description of Gold Centrifugal Concentrator

Gold centrifugal concentrator is a machine that was patented in China. It is an efficient machine that is useful in the recovery of free gold in all ranges of particle size. It is most especially useful for recovering fine gold which gets lost during the operation of gravitational concentrators. It is not only used for alluvial/placer gold mining, but it can also be used for the recovery of natural gold from rocks that are hard, for replacing amalgamation and recovering of gold from the tailings.

Working Principle of Gold Centrifugal Concentrator

The rotor of the centrifuge rotates at a high speed at a certain number of revolutions, and the ore slurry is sent to the inner wall of the rotating drum by the ore feeder and the orifice in two places. The ore pulp rotates with the drum at high speed. Under the action of centrifugal force, heavy minerals deposit on the inner wall of the drum and rotate with the drum. At the same time, it needs to continuously give backwash water from the outside to the middle layer of the centrifugal rotor A certain differential speed rotates with the drum. During the rotation, a certain helix angle flows from the feed end to the ore discharge end in the direction of the drum slope to the end, and is discharged through the ore separator at the end, which is the tailings. Work for about 4-6 hours, after the rotor inner wall is enriched with a certain amount of concentrate, stop feeding into the rotor. After the tailings are discharged, the ore discharge separator automatically turns away from the original normal position to prepare to intercept the concentrate. Then, the high-pressure flushing water valve is opened, and the high-pressure flushing water flushes down the concentrate deposited on the inner wall of the rotor. After the concentrate is drained, the equipment is re-opened to work and the cycle is performed.



Application Area of Gold Centrifugal Concentrator

The centrifuge is a sorting device that separates minerals with a large difference in gravity in the centrifugal force field, and is one of high-efficiency sorting devices. It is mainly used for initial enrichment of concentrates of precious metals such as placer gold /alluvial gold and crushed rock gold.

Main Structure of Gold Centrifugal Concentrator

The centrifuge is composed of feed pipe, rack, tailings trough, drive motor, vertical shaft and mineral processing parts.
