The invention relates to the technical field of ore dressing, especially to a mixed concentration grade control system and control method. The mixed concentration grade control system comprises a human-machine interface unit, a detection unit, a central data processing unit and an execution unit. Setting parameters related to mixed concentration grades are set in the human-machine interface unit; the detection unit detects actual parameters related to the mixed concentration grades in real time; the central data processing unit carries out intelligent analyses and determination on the actual parameters and the set parameters directly; and according to the analysis and determination result, the execution unit controls correlated motion and adjusts the set parameter values, so that all actual parameters are kept in a set parameter range. According to the invention, on the basis of automatic control, the concentration grade can be controlled between a set upper limit and a set lower limit stably, thereby guaranteeing the good concentration product quality.
Description
technical field [0001] The invention relates to the technical field of ore dressing, in particular to a mixing and beneficiation grade control system and control method. Background technique [0002] Mixing and concentrating is a very important part of the whole flotation process, and the concentrate selected by mixing and concentrating is directly related to the quality of the final product. [0003] The production process of mixed flotation is roughly as follows: [0004] The ore slurry overflowed from the grinding cyclone enters the mixed roughing flotation machine after being stirred, and the concentrate that meets the requirements is flotationed by the mixed roughing flotation machine and directly enters the roughing pump box, and is transported to the copper-molybdenum mixed thickening machine through the foam pump. machine; [0005] The overflow product of the mixed roughing flotation machine enters the stirring tank, and the underflow pulp obtained by the mixed rou...
