In the actual production process, the structure parameters of the heavy medium cyclone can't be changed, the change of the raw coal nature is uncontrollable. So the stability and optimization of process parameters is the key factor to the full realization of heavy medium cyclone separation. The main process parameters affecting the cyclone separation are: heavy medium density, magnetic material content, the medium inlet pressure, the feeding quantity, etc. The effect of process parameters on the separation is mainly through affecting the actual separation density. Based on the analysis of the influence of process parameters on the separation density, firstly establish the mathematical model between the actual separation density and the various process parameters, then establish the relationship model of product structure and the actual separation density, in order to determine the best separation process parameters in accordance with the requirements of product structure. The actual production situation shows that the model can better reflect the actual production to some extent, but there is a certain deviation, so it also needs to be improved.
