Ground Calcium Carbonate Manufacturing Process

Ground calcium carbonate (GCC) is mechanically crushed and classified, and its particles are mostly in irregular shapes such as cubes, polygons and cuboids. According to its original particle size, it is divided into coarse ground calcium carbonate (>3 µm), fine ground calcium carbonate (1-3 µm) and ultra fine ground calcium carbonate (0.5-1 ...
