    Low filling degrees and low percentage of critical speed do not allow an efficient ball charge action on the material. High filling degrees and high percentage of critical speed lead to ball charge centrifugation and very little grinding efficiency. Mills with high percentage of critical speed can be operated with low filling degrees

  • Optimization of continuous ball mills used for finish Science Direct

    During the last decade, semifinishgrinding plants have been used more and more for the energy efficient grinding of highquality cement. In 1999, it was found that by decreasing the ball charge filling ratio it was possible to lower the specific energy demand for grinding significantly. It was obvious, too, that the L/D ratio

  • Ball mill Wikipedia

    It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. The grinding
