High-quality calcium carbonate is selected as raw material, after pretreatment such as beneficiation, cleaning, crushing and homogenization, it is crushed by large-scale ultra-fine crushing production equipment, and then finely classified. It has the characteristics of stable chemical properties, high whiteness, less impurities, reasonable particle size distribution and no radioactivity.
