[0002] Calcium carbonate is a valuable resource with a wide range of uses. It has been widely used in the history of human civilization for its wide distribution in nature and easy access. As an important building material, it has a long history of mining. In modern industry, limestone is the main raw material for making cement, lime, and calcium carbide. It is an indispensable flux limestone in the metallurgical industry. After ultra-fine grinding, high-quality limestone is widely used in the manufacture of papermaking, rubber, paint, coatings, medicine, cosmetics, feed, sealing, bonding, polishing and other products. According to incomplete statistics, the ratio of limestone consumed in cement production to building stone, lime production, metallurgical flux, and ultra-fine calcium carbonate is 1:3. With the continuous advancement of science and technology and the development of nanotechnology, the application field of limestone will be further broadened. In the existing technology, the production and preparation of calcium carbonate requires a carbonization reactor.
