The centrifuge is a new type of equipment developed in modern times to recover useful minerals in fine alluvial gold mud. For example, the fine placer gold ore has a poor sorting effect in the gravity field, and sometimes it is even difficult to sort. In the centrifugal force field, the material is subjected to centrifugal force much larger than gravity and combined with flow film beneficiation, it can solve the problem of recovering fine-grained gold from 74~10μm placer gold ore.

Centrifuge Beneficiation Principle

centrifugal concentrator structure and principle

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.
