A Model Predictive Control for Coal Beneficiation Dense ...

Jan 01, 2014· Dense medium cyclones (DMCs) are used as the main coal benefication process in modern coal washing plants because of their high capacity and efficiency (Chu et al., 2009). The relative density of the dense medium used to enhance the separation is the key factor that affects the quality of coal after this DMC circuit.

THE DEVELOPMENT OF DYNAMIC MODELS FOR A DENSE …

Dense medium separation (DMS) plants are typically used to beneficiate run-of-mine (ROM) coal in coal metallurgy. These plants normally make use of a dense medium cyclone as the primary processing unit. Because of the deviations in the ROM quality, the production yield and quality become difficult to maintain.

Dense Medium Cyclone

From the early 1960's until the mid 1980's, dense medium cyclone circuitry design technology did not change appreciably. The basic design, which was both highly flexible and highly efficient, was consistent with technology developed by the Dutch State Mines ("DSM") in the mid 1940's. During this period, the "typical" dense medium cyclone circuit was designed to process raw coal ...
