| Abstract: |
| To solve the problems of unreasonable steel ball size ratio, low grinding efficiency, and high consumption of steel balls in the ball mill of Mirador Copper Mine, without changing the crushing equipment and process, experimental studies on steel ball ratio were conducted for the Φ7.9×13.6m ball mill in the Ecuadorian copper mine. Through theoretical calculations and analytical testing, the initial ball loading and supplementary ball charging systems were determined. The rationality of the initial and supplementary ball charging systems was verified through discrete element simulation experiments, providing a basis for industrial application on-site. |
