Özet
Experimental investigations on the wet ultra fine grinding of calcite (CaCO3) powder in stirred bead mill are presented. The net volume of the milling chamber is 0.75 liters. The grinding chamber is made of ceramic to reduce the wear on the materials of the mill. For cooling purposes, the grinding chamber is also equipped with a water jacket for cooling. The grinding media selected for the tests are 1 mm diameter zirconia beads. The influence of some operating parameters such as solids concentration (%), grinding time (min.), stirrer speed (rpm) and bead filling ratio (% of net mill volume) on the size distribution of ground product is discussed. The effect of grinding time on the particle size distribution and fineness is highly significant and positive. The variables stirrer speed and bead load have also positive effects on the grinding.
