Large calcium carbonate
Large calcium carbonate also known as floor calcium carbonate, is made by normal exceptional calcite, which has higher purity and whiteness. The dimensions ranges from unEPT400 mesh which is named primary merchandise, to 3000 mesh or previously mentioned, depending on your prerequisite.
Weighty (Floor) Calcium Carbonate is extensively employed as filler and improver in plastic, paint, paper-creating, rubber, pharmacy, feed, daily chemical, ceramics, adhesives and ink industry.
