effect of temperature in grinding in a ball mill

  • Optimization of mill performance by using

    mill performance could become worse or better by putting in a new shell liner. Data from pilot plant test work illustrates the influence of the shell lifting effect on the grind for a primary grinding duty. Figure 5 shows the evolution of the mill discharge product size in relation to the lifting effect of the liners.

    As part of the grinding process calcium sulfate is added as a set regulator usually in the form of gypsum (CaSO 4.2H 2 O). Natural anhydrite (CaSO 4) may also be added. Cooling is necessary to limit the temperature rise of the cement. This is done by a mixture of both air-cooling and water-cooling including spraying water inside the mill.
