Grinding calcium carbonate down to size
Ground calcium carbonate grains can be as coarse as 1,300 microns in poultry feed or as fine as 2 microns in paper coatings. Milling the limestone to the correct particle size distribution is a test for GCC processing. But addressing this challenge successfully makes the difference between high and low-quality calcium carbonate materials.
