Precipitated light calcium carbonate production equipment and process
Precipitated light calcium carbonate is a kind of calcium carbonate. The light calcium carbonate powder with fineness specifications of 125 mesh, 200 mesh, 225 mesh, 300 mesh, 600 mesh, 800 mesh, and 1250 mesh can be obtained through light calcium carbonate processing equipment. It is widely used in papermaking, rubber, plastics, paint, water-based coatings and other industries. With the improvement of light calcium carbonate production equipment technology, the application field is also expanding, such as high-end cosmetics, putty powder, medicine, daily chemicals, coatings and other fields. With the continuous improvement of fineness, the price of light calcium carbonate powder is showing an upward trend. Recently, Guangxi Province has invested 100 billion yuan to promote the development of the calcium carbonate industry, and further promoted domestic investment in the production of light calcium carbonate powder.
Precipitated light calcium carbonate production process: firstly, limestone and other raw materials are burnt to produce lime (the main component is calcium oxide) and carbon dioxide, and then water is added to the lime to produce lime milk (the main component is calcium hydroxide), and then carbon dioxide is introduced into the carbonized lime milk. The calcium carbonate precipitate is formed, and then it is prepared by dehydration, drying and grinding, or it is prepared by the metathesis reaction of sodium carbonate and calcium chloride to generate calcium carbonate precipitate, which is then dehydrated, dried and ground. The grinding process includes coarse crushing of light calcium carbonate. In the grinding stage, the fine stone from the raw material warehouse is put into the light calcium grinder for grinding, and the ground powder is sent to the super fine grade machine. The fineness can be adjusted between 200-2000 mesh.
