Abstract:
Spiral concentrator separation is a resorting method using flow membrane gravity and inclined flow sorting, which has the advantages of large processing capacity, low energy consumption, no pollution, high separation efficiency and wide separation range, and is widely used in the field of mineral processing. This paper deeply expounds the key technical problems of the spiral concentrator and the characteristics of different types of spiral concentrator. At the same time, this paper also systematically combs the motion state of the spiral concentrator flow membrane, the particle movement trajectory and the optimal design of the groove surface. Finally, the application of spiral concentrator separation technology is summarized and the development trend of this technology is discussed. The content of this article can provide reference for the development of spiral concentrator separation technology.
