Heavy calcium carbonate

Heavy calcium carbonate also called ground calcium carbonate, is produced by natural superior calcite, which has high purity and whiteness. The size ranges from under 400 mesh which is called primary products, to 3000 mesh or above, depending on your requirement.

Heavy (Ground) Calcium Carbonate is widely used as filler and improver in plastic, paint, paper-making, rubber, pharmacy, feed, daily chemical, ceramics, adhesives and ink industry.
