| Abstract: | The design concept of continuous discharge separation cone is proposed. The stress of two-component particles is analyzed from radial and axial directions. The separation mechanism of particles and the continuous discharge characteristics of heavy particles under the coupling action of reverse flow field and centrifugal flow field are deduced. In this paper, a simulation test model is established. Taking silica particles and copper powder as the separation object, under the conditions of reverse flow pressure of 10000pa and diameter axial ratio of 1:2.7, it is verified that the enrichment and recovery effect of the cone is good when the rotating speed of the inner cone is 700R / min. The research shows that the continuous discharge separation cone is of great significance to the research and development of continuous beneficiation equipment. |
