Based on motion and impact analysis, a theoretical model is presented for optimization of grinding performance of a tumbling ball mill. The motion of ball media in the tumbling ball mill is analyzed. The impact parameters of the ball media caused by the falling motion are deduced. The impact and attrition grindabilities are studied. The grinding performance is expressed as the proportion of grindability of all collisions to that of the collisions of ball media in the arc of the shell at a theoretically suitable speed, and is calculated from the point of view of the separation layer. The mathematical model is established and program coding is implemented to optimize grinding performance for the tumbling ball mill. An example of design calculations is given which shows that the grinding performance under the optimized operation parameters is improved significantly.
