limestone grinding particle size distribution

  • Dry Grinding VS Wet Grinding - Mineral Processing & Metallurgy

    The effect of the coarser particles on the grinding rate of the finer ones was investigated by introducing coarse quartz particles in the natural size distribution environment of limestone. Results of Tests 1 and 2 in Table 6 show that 50% replacement of the 20/28 mesh limestone particles by same size quartz particles reduced the breakage rate of limestone particles by only about 2.5%.

  • Fine grinding of limestone and dolomite for the paper industry

    After flotation, the carbonate concentrate will have to be ground to 50 to 90% - 2 microns for various applications where a specified particle size distribution is required. Different kinds of fine grinding equipment have been tested for this purpose. Mills tested include attrition mills, annular ball mills and vibro-energy mills.
