  • 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.

  • Analysis of ball mill grinding operation using mill power

    Thus, a significantly large amount of electrical energy is consumed in the ball mill grinding operation. It is, therefore, important to establish the optimum values of various mill operating parameters, such as the mill speed, ball load, ball diameter and particle load, from the energy consumption point of view.
