Get PriceMay 11, 2021 In the ball mill, Impact and Attrition both are responsible for the size reduction Rapidly moving balls are used for the comminution of brittle material. Construction of Ball Mill. The ball mill consists of a hollow metal cylinder mounted on a shaft and rotating about its horizontal axis. The cylinder can be made of metal, porcelain, or rubber.
Get PriceThe milling process was conducted in a SPEX 8000M mixer-mill using a hardened steel vial and chromium steel balls under an inert argon atmosphere. During milling, the ball-to-powder weight ratio (BPR) was maintained constant at 5:1 for all experimental runs. ~8 grams of graphite was milled at different times (0 to 16h).
Get PriceThey extend to almost the full length of the shell and occupy about 35% of the shell volume. In such mills, attrition forces predominate but impacts also play a part in size reduction. They are classed as intermediate grinders and are more useful than ball mills for milling sticky materials. 43.6 Selection Criteria for Size-reduction Equipment
