Development and test study on a new type of separation classifier

On the basis of the analysis of liquid-solid fluidized bed performance, a new type of separation classifier was developed and the working principle and characteristics of it wereanalyzed. In the coal flotation tailings as the study object, no top water and top water separation studies were testedrespectively. The results show that the separation classifier forcoalflotation tailings has good separation effect on reducing ash and grading. At the end of cone increasing rising top water scavenging process is helpful to improving the separation classification effect, andacquiringash 28.48% recovery from high ash coal flotation tailing and 23.64% yield of +0.125 mm of low ash coal, with good separation efficiency and application prospect of wide.
