  • Ball mill Wikipedia

    The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry.

  • How Mill Load/Charge is Estimated Grinding

    Modern mills operate with load cells and mill optimizer's which synchronize the mill weight, power draw, ore feed and weight with density control. Where optimizers are not used, the rule of thumb for a overflow ball mill is a ball load up to about 12 inches below the trunnion discharge- this allows bed expansion by the slurry filling the voids and lifting the steel balls.
