Computer-aid analysis, simulation and optimization of coal preparation circuits

The technique of computer-aid analysis, simulation and optimization of coal preparation circuits has been successfully applied and developed by CLI Corporation. Using this technique, the washability of raw-of-mine coal can be analyzed, the Ep values for different gravity-separation devices at different separation density can be evaluated. Based on these, a comprehensive computer code can be developed for the overall circuit simulation and optimization. This technique is particularly valuable for process design, operation, and modification. In this paper, the principles and the strategies of the technique are presented, and some typical applications are described.
