Improvement of centrifugal separation on the basis of pneumatic turbulization of separator cone wall layer

The use of centrifugal separators is widespread in the processing of ores and technogenic raw materials, which contain fine particles of noble metals with increased density. Centrifugal separators provide high separation rates of particles of different densities in the processing of minerals compared to other methods of processing. When using centrifugal separators in industry, it is not always possible to achieve the desired results in terms of the final products of centrifugal separation. Many parameters characteristic of centrifugal separators create problems in determining the optimum mode of operation of the apparatus. In addition, the high water consumption has a negative impact on the operating and environmental costs of material processing. This calls for a detailed study of the segregation of material in the nearwall layer of the centrifugal separator cone. In centrifugal separators, the use of compressed air to turbulence the boundary layer from inside the cone is different from the use of water. The use of air to turbulate the boundary layer decreases the resistance to the flow of mineral particles compared to water, which in turn leads to an increase in centrifugal separation. The use of compressed air for turbulization of the near wall layer of the separator cone allows to realize the circulation and accumulation technology of mineral and technogenic raw materials processing in order to increase the extraction of finely dispersed particles of high density.
