Generally 10:1 and 5:1 BPR is recommended for low energy ball mills and 100:1 and 50:1 BPR is recommended for high energy ball mills. BPR is also depends upon the material as well as the.Effect of BalltoPowder Ratio on Morphology, Structure, ,712 Thus, the ball milling efficiency was improved owing to the increased collision frequency between the balls and powders. When the BPR was increased to 15:1, the circularity reached 0.855, which indicates particle’s shape was close to be circular.(PDF) Properties of pulverized kaolin particles via ballto ,611 Kaolin particles reached an average of 944nm in size after milling for 4hr under balltopowder weight ratio of 4, which is much smaller than unpulverized kaolin particles at the average mean.
