Gravity Centrifugal Gold Concentrator / Small Gold Refining Machine

Centrifugal Gold Concentrator is a new type of gravity concentration equipment for gold separating and other high density minerals. The centrifugal machine has many competitive advantages compared with other concentration machines which create high returns for the investors.

We have fully-continuous (Knelson Continuous Variable- Discharge, CVD type) and semi-continuous(Batch type) centrifugal gold concentrators.

Since 1985, three models of centrifugal concentrator 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 of0.074mm, 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.

Specification of concentrator.

Applications for gold concentrates:

The application shows that gold grain size less than 5mm, the recovery rate up to 90%, while gold grain size less than 2.5mm, the rate can be 92%.

Machine structure for gold concentrates:

Water Jacket gold concentrator consists of pipelines, mainframe, tailing chute, drive motor, vertical shaft and separation device.
The separation device is cone unit includes two layers; the inner layer is made by stainless steel plate, with circle gratings and small holes on the wall, the outer layer is made by mild steel plate. The two layers form a close water jacket system.

Operation principle for gold concentrates:

The main shaft is a hollow shaft, the pressurize backwash water come from the shaft, then goes into the separation unit, the water spray from holes to the gratings. During the process, the pressure of the water shall be 0.06-0.15MPa.
The slurry which is mixed with water and grinded ore and sand will be injected to the mainframe. With the heavy centrifugal force, the slurry will be move upward along the cone body, the light particles will be extracted from the upper part of cone, then discharge through the tailing outlet. The heavy particles will be stay in the gratings of the inner layer.
