Grinding: A limestone mill is used to grind the crushed limestone into a fine powder. In this procedure, the mill's grinding rollers and grinding ring crush the limestone powder that was previously fed into it. Classification: A classifier separates the fine powder from the coarse powder in the pulverized limestone powder.
