The production process of nano calcium carbonate mainly uses carbonization method, mainly including batch carbonization method, continuous spray carbonization method, hypergravity carbonization method and other production methods.

The production process of heavy calcium carbonate is mainly crushing, ultra-fine crushing, grading and surface modification.

The production process of light calcium carbonate generally uses limestone as raw material to prepare precipitated calcium carbonate products by calcination, digestion, carbonization, separation, drying, grading, packaging and other processes.
