Influence of ball and powder filling ratios (Jb and fc) on the dry grinding process of calcite
Turkey has important quantity of industrial minerals and calcite is one of them and is used as filler in the industries such as plastics, rubber, and paint, to gain a variety of features to products. In order to use calcite as filler, some specific properties such as fine product size are required. In the world, conventional ball mill technology is used to obtain calcite with micronized on the industrial scale. In the mill, ball filling ratio (Jb) and powder filling ratio (fc) directly affect product size, energy consumption, and grinding costs. In this study, influence of important operating parameters such as ball and calcite filling ratios (Jb and fc) on the grindability of calcite ore was examined to obtain a fine product (<100 ?m) in the conventional ball mill. The batch test results show that the parameters play an important role in the fine grinding process of calcite.
