Centrifugal gold concentrator is a new ore beneficiation equipment,which is improved from similar products in Canada and South Africa.It is mainly applied to recover the visible gold in alluvial gold or rock gold,as well as flotation concentrates and gold tailing dealing.

The centrifugal concentrator is carried out in the centrifugal force field. It is characterized by using the centrifugal force of the fine mineral particles in the centrifugal force field to greatly exceed the gravity, thereby accelerating the sedimentation speed of the mineral particles (that is, increasing the radial sedimentation speed) and expanding The difference in the sedimentation velocity of different densities of ore particles has been improved, thereby strengthening the gravity beneficiation process of the sand-gold mine.
When the mineral particles move in a circular motion in the centrifugal force field, the centrifugal force generated is related to the quality of the mineral, the radius of the centrifuge drum, and the linear speed (or angular velocity) of the centrifuge operation. The centrifugal acceleration of the minerals in the centrifuge is several times that of the general gravity chute, which can greatly accelerate the sedimentation speed of the mineral particles.
The main parts of gold concentrator includes feeding pipe, drain pan, main shaft, spring, motor, tailing discharge mouth, belt. high-speed pin create power centrifugal force, in the process of gravity separation, light material would be discharged, gold gathers. Nowadays, the centrifugal concentrator is widely used for the recovery of gold, tungsten, lead, manganese, iron, etc.
Gold centrifugal concentrator is useful in the gold recovery in all ranges of particle size. It is most especially useful for recovering fine gold which gets lost during the operation of gravity concentrators.
The application 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%.
Advantages
1. Application shows that the recovery can be as high as 99%, and the concentrating ratio is up to 1,000 times. In recovering the natural gold in lode ore with size -0. 074mm, the gold is up to 98%, For 0.04mm in particle size, the gold recovery is 97%.
2. Strong centrifugal force produced by high speed spin strengthens the process of gravity separation and effectively recover the fine ore particles.
