| Abstract: | The effecting of feed pressure and suspension density on clean coal quality were tested, the separating result of different size range and factors influencing separating-size of fine coal cleaning with dense-medium cyclone were studied in detail. The results show that the particle size distribution of the magnetite, the viscosity of the suspension, and the solid-liquid concentration of the suspension are key factors determining the separating-size of fine coal cleaning with dense-medium cyclone. |
