2024年10月13日 Effect of ball size on ore grinding performance Ball milling is a powerful tool for extracting metals from ore. The key to ball milling is the size of the balls that are used. The larger the balls, the more force is applied to the ore and the greater the chances of breaking it down into smaller pieces. However, there are also factors that can ...

Ball sizes that are used in grinding should be large enough to break the largest and hardest ore particles. Optimal ball sizes depend on the feed/product size ratio, mill dimensions, and breakage kinetics parameters. Usually, larger balls grind coarser ore particles efficiently and smaller balls grind fine particles more efficiently [59].
