Abstract: The principle of interference bed and the best range of feed size are introduced. The analysis shows that increasing the bed density and decreasing the rising water flow rate can enhance the function of density separation, and then improve the separation effect of interference bed.Adding heavy medium into the interference bed can increase the bed density, significantly improve the clean coal index, and greatly improve the separation effect.

Key words: interference bed, density, heavy medium, feed size ratio, Hδ50
