In order to ensure that the emulsion concentration keep steady in the emulsion proportioning system, a set of mine emulsion concentration automatic proportioning system control of fuzzy adaptive PID control strategy was designed based on the analysis of ratio of emulsion automatic control principle, and the field measurement was carried out. From two aspects of emulsion flow transient smaller and larger were measured, it was verified that the design of fuzzy adaptive PID control was accuracy. The result shows that the concentration of fuzzy adaptive PID has faster response, smaller overshoot and faster to reach steady state, and the advantages of stronger antiinterference ability, which can realize the optimum control for mine emulsion automatic proportioning system concentration.
