Abstract In fine grinding of cement in a ball mill, it is sometimes impractical to grind finer in a dry state. Even though the chemical reactivity requires the material to be dry ground, it is sometimes necessary to use different breakage machines to ob tain the product, but it is usually more expensive, requires more energy and reduces capacity.FINE GRINDING OF HEMATITE IN PLANETARY MILL AND ,2018-8-7 · Figure 2.4 Schematic configuration of the planetary ball mill 15 Figure 2.5 Type of ball motion in planetary ball mill 16 Figure 2.6 Change in specific surface area of calcium titanate (CaTiO 3) at various mill rotational speeds and grinding times 20 Figure 2.7 XRD patterns of the talc samples ground for various times;
