The grinding tank was also equipped with a water jacket for cooling. Zirconia beads with diameters of 0.6–1.0 mm and 1.27–2.0 mm and a density of 6.1 g/ml were used as the grinding media in the grinding basket. To grind with this machine, the GCC slurry was poured into the grinding tank, and the grinding basket was lowered down to cover it.
Each crystalline form of calcium carbonate is deformed plastically, and in a flowing together and apart of the grains a grinding equilibrium is established with an equivalent particle size of about 860 nm. The precipitated calcite suffered a marked reduction in specific surface area of from 20 to 3 m~/g.

The dependence of the pressure filtration properties of ground calcium carbonate slurries on the grinding results obtained by a stirred media mill was investigated in the study. The results showed that the average specific cake resistance α av correlated relatively well with small representative particle sizes, such as D 10 and D[3,2].
The produced calcium carbonate (80% <50 μm) needs to be ground finer in order to be suitable to use as a paper coating material (target: 60% <1 μm). The calcium carbonate used for coating is typically delivered as a slurry, so water can be added at the grinding stage.
Taking into account the quality of the medium itself and the control of the particle size of the calcium carbonate after grinding and the current of the grinding machine, the amount of the medium is 1/2~3/5 of the grinding volume of the grinding machine, and the types of media used by different grinding units are different, …
