Haiwang LXA spiral separator is the separation equipment which separate the concentrate and tailing in accordance with the difference of density and particle size. When the slurry flows into spiral separator, as the function of gravity, centrifugal force, friction and water flow pressure are different, thus the motion trial of material with different particle size and density inside spiral separator are different. Finally, concentrate of high density and big particle size gets discharged from the inner edge of spiral separator; tailing of low density and small particle size gets discharged from the outer edge of spiral separator. The spiral separator is the common used equipment for the classification and separation of fine particle minerals in beneficiation factory.
