Abstract: Density of dense medium suspension is an important factor affecting the effect of dense medium washing. Effective
control of dense medium suspension can significantly improve the output quality of clean coal and increase the comprehensive
benefits of washing products. From this point of view, the application of dense medium suspension density control system in coal
preparation was explored. Combining with engineering practice, this paper made a detailed analysis of the composition and
application of dense medium suspension density automatic control system, hoping to provide reference for similar work in other
coal preparation plants.

Key words: coal preparation plant; dense medium coal preparation; suspension density; ash content
