In view of the causes of the wear of the inlet of the HM cyclone, the movement of the fluidized particles and the impact on the wall of the fluidized bed are analyzed. The mathematical model of the particle erosion parameter calculation is proposed. According to the actual situation of coal HM separation, the structural parameters of various particles and hydrocyclone were calculated, and the actual influence on erosion was analyzed, which provided the theoretical basis for optimizing the structural parameters of cyclone. As a result of the research phase of industrial products, in the actual production showed good wear resistance and satisfactory sorting results.
