Description

technical field [0001] The invention relates to an intelligent dosing system and a dosing method for coal slime water in a coal preparation plant, belonging to the technical field of coal washing. Background technique [0002] In recent years, with the substantial improvement of coal mining mechanization, the proportion of fine-grained coal content in selected raw coal has been increasing, and the concentration and treatment capacity of coal slime water have also increased, especially for high-ash fine mud that is difficult to settle. Slime water is very difficult to deal with. Many factors have made the slime water treatment system of the coal preparation plant the most complex, most expensive, and most difficult to manage important link that restricts the economic indicators and social benefits of the whole plant. The treatment effect directly affects the reuse of washing water and closed-circuit circulation. It also has a great influence on other aspects of the coal prep...
