Calcite Production. Step 1: The incoming minerals are pulverized and transferred to ball mills. Step 2: These powders, which are crushed by the balls as they are in the cement factories, are also sieved from the sieves and separated into the desired grades. Step 3: Thus, 3-micron, 5-micron, 10- micron bags are sold separately.
