Abstract:In view of the problems of grinding classification instability and poor grinding effect in the grinding classification system of Wushan Copper Mine, the grinding classification process is analyzed and improved. After the improvement, the automatic control of grinding concentration, fineness of grinding products and particle size composition of grinding products are improved through the automatic control system of grinding water supply, automatic control system of raw ore pump level and automatic control system of grading pressure, accurate calculation and given water replenishment at each point, and the automatic control of grinding concentration is realized. The production application results show that the concentration of semi-self-grinding, ball grinding and raw ore overflow are more stable, the grinding classification effect is improved, the level of the pump pool is more stable, and the production process is more balanced and efficient.
