Abstract: In view of the unreasonable addition of chemicals in the slime water concentration process, the waste of chemicals increases the cost of the coal preparation plant, and even leads to unsatisfactory overall concentration effects and inability to meet the feed requirements of the press filter after concentration. Designed an intelligent dosing control system under different working conditions of slime water thickening, real-time identification of slime water thickening feed conditions, based on overflow turbidity (thickening effect) and underflow concentration of thickener (filter press feed requirements) and The chemical consumption is the optimization goal, and the chemical dosing system based on the MOPSO slime water concentration process is designed. Through simulation verification and industrial field application test, good results are obtained.
