Özet
This study focused on ultra-fine grinding of calcite powder (CaCO3) using a vertical stirred ball mill. The influences of various operating parameters such as stirrer speed (rpm), ball filling ratio (J), powder filling ratio (fc), solid ratio (wt.%) and grinding time were studied under wet conditions. The experiments were carried out in a batch mode of operation. The experimental results were evaluated based upon product size (d50), specific surface area (m2/g) and width of particle size distribution. As a result of this work, the optimum grinding test conditions were found to be 840 rpm for stirrer speed, 0.70 for ball filling ratio, 0.100 for powder filling ratio, 50% for solid ratio and 20 min for grinding time. It was also observed that stirrer speed, ball filling ratio and grinding time were directly proportional whereas powder filling ratio and solid ratio were inversely proportional to product fineness and specific surface area. The width of particle size distribution decreased with decreasing product size for all grinding conditions.
