Abstract: The shortcomings of the density control system for heavy media suspension in the current coal preparation plant were introduced. The intelligent control system of heavy media separation suitable for different coal quality characteristics in LinHuan Coal Preparation Plant was proposed. The system was mainly composed of the following parts: relationship between ash and mineral content, automatic identification of raw coal production source information, automatic adjustment of online ash analyser parameters, closed loop control system based on clean coal ash content. After intelligent control of heavy media separation was applied. The processed raw coal production source information and ratio could be automatically identified by the system, and the parameters of the online ash meter could be automatically adjusted. The clean coal ash content after heavy media separating was relatively stable, and the product qualification rate was improved.
