在矿石硬度、给矿粒度、钢球配比、磨矿浓度及溢流细度等参数相同的条件下，通过增加钢球装填量和缩小出料口进行提高磨机处理量的试验研究。试验表明，适当缩小出料口，处理量明显增加，而钢球消耗和负荷确明显减少和降低。 Under the condition of the same parameters of ore hardness, ore particle size, steel ball ratio, grinding concentration and overflow fineness, the experimental research on increasing the processing capacity of the mill by increasing the filling amount of the steel ball and reducing the discharge port was carried out. Experiments show that, properly reducing the discharge port, the handling capacity increased significantly, while the ball consumption and load obviously decreased and decreased.
