Calcium carbonate
Calcium carbonate is a chemical compound with the formula Ca CO 3.It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of eggshells, snail shells, seashells and pearls.

The particle size of the heavy calcium carbonate powder is more uniform
It is well known in the industry that there are different processes for the processing of heavy calcium carbonate powder in dry and wet methods. Dry processing is more conducive to achieving industrial scale and a certain degree of product refinement. Therefore, many companies have chosen to use air classifiers to obtain more refined heavy calcium carbonate powder.
