These calcite blocks with different roughness will be used in the test of surface wettability and surface energy. The calcite samples used for grinding and flotation was crushed to about 2 mm, and then ground by a ball mill and a rod mill respectively. The ground products were screened and classified using the Taylor standard sieve.

Since the particle size, shape, specific surface area, and purity of the ground calcium carbonate (GCC) decide its usability in the paper, paint, and plastic industries, the effect of grinding is important. However, the effect of stirred and ball mill grinding on the particle shape of GCC by dynamic image analysis (DIA) is still lacking in the literature. Therefore, the aim of this study is to ...
