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 ...

1. Fine grinding in the mining industry. It has been estimated that approximately 2% of the world's energy usage is applied to mineral comminution, and around a quarter of this is used specifically in metalliferous ore grinding [1] where it is typically the most energy intensive set of operations [2].The purpose of comminution in ore processing is to reduce particle size in ...

In the equation, E 1 is the total power demand normalized by batch size (mol), and E 2 is the estimated power demand normalized by per mole of product (mol). As shown in Fig. 3., E 2 of the ballmilling process (K 2 CO 3 /KLBM, green ball) increased slightly from 10 to 38 kWh mol −1 (from 5 to 25 min). As the duration increased, extra energy was squandered with no yield increase.
