  • Ball mill media optimization through functional ...

    Numerous torque mill tests, in addition to the growing plant data base compiled to date, show that media charging near the size that provides highest ball mill grinding efficiency provides a degree of robustness with changing ore grindability. It is rare that the media is incapable of breaking the largest particles as they become tougher.

  • Ball mill media optimization - Metcom Tech

    • Test mills used for media sizing investigations need to be reasonably large (at least 0.4 m in diameter was suggested), depending on size of balls and ore being tested. • Ball surface wear rate is approximately constant, but with variations due to hardness, and other factors. Consumption is closely related to total ball charge surface area.

  • Ball Charge and Grinding Efficiency - Grinding ...

    The volume of grinding media in a mill is directly related to grinding efficiency. The higher the volume of grinding media the more effective the grind. Balls must be added to maintain the media load and mill power draw. The power draw increases as balls are added and decreases as media wears down: add balls.
