Description

technical field [0001] A centrifugal beneficiation device and a beneficiation method thereof relate to a fine-grain mineral beneficiation device, in particular a continuous fine-grain mineral centrifugal beneficiation device and a beneficiation method thereof. Background technique [0002] Due to the characteristics of fine particle size, poor mineral buoyancy, severe gangue mineral mudification, and large interference of refractory ions, fine-grained minerals make it difficult to recover minerals, and it is difficult to obtain qualified grade concentrate products by flotation. Gravity separation, jigging, etc., has a poor separation effect, which makes the separation of fine-grained minerals one of the difficult problems in the field of mineral processing technology. [0003] Centrifugal beneficiation technology uses centrifugal concentrator as a device to separate target minerals and gangue minerals. Centrifugal beneficiation technology has the advantages of rapidity, sim...

Problems solved by technology

This method strengthens the stratification of materials according to the density in the centrifugal field, but does not consider the design of the cone angle of the centrifugal drum. For materials with different particle sizes and densities, the cone angle of the centrifugal drum has an important role in the centrifugal separation of materials. Significant impact, which makes the separation efficiency of the device in the separation of materials with different particle sizes and densities is not high, and the scope of application is limited
