Intelligent Control and Optimization of the Coal Slime Flotation

The inchoate algorithm for the coal slime flotation control is the feed-forward control to the feed concentration and the reagent quantity. This control model is widely utilized because of the easy realization once the used sensors are reliable. However the control results are usually not so good as it cannot adapt the quality fluctuation of the feed, obtain the on-line quality of the feed and the products, and also cannot statistically calculate the flotation recovery and other production management information. The appearance of the coal slurry ash detector provides the new method for resolving the problems above. This paper studies how to increase the production rate and decrease the reagent consumption through the optimizing control under the premise of the accepted concentrate ash. The industrial application of the intelligent and optimal control of the coal slime flotation results in a high concentrate recovery and a decrease of the reagent consumption, ensuring a highly efficient operation.
