A pilot-scale grinding technology of ceramic medium stirred mill was proposed in this study. Based on the specific productivity and grinding efficiency, the appropriate grinding parameters were ascertained as follows: material ball ratio of 0.7, ceramic ball medium size ratio (10 mm: 15 mm: 20 mm = 3:2:5), stirring speed of 110 rpm, grinding concentration of 50%, and medium filling rate of 90%.

Increasing the filling rate increases the probability of the steel balls to grind the ore and the self-grinding effect of the ore. When the filling rate of steel balls is 45%, the load of the ball mill is the maximum, and when the filling rate exceeds 45%, the load is greatly reduced with the increase of the filling rate.
