Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks and minerals, such as limestone, chalk, and marble. Calcium carbonate is also found in the shells of marine organisms, such as oysters and clams.

Ground Calcium Carbonate Processing refers to the process of converting raw calcium carbonate stones into a fine powder that can be used in various industrial applications. The process typically involves several stages, including crushing, grinding, and classification.

Crushing: Raw calcium carbonate stones are first crushed into smaller pieces using a crusher.

Grinding: The crushed calcium carbonate is then ground into a fine powder using a Ground Calcium Carbonate(GCC) Grinding Mill, such as a ball mill, Raymond mill, vertical mill, or roller mill.

Classification: The ground calcium carbonate powder is then classified by a classifier, which separates the fine powder from the coarse powder.

Coating: The fine calcium carbonate powder may be coated with a surface treatment agent to improve its properties or to make it more compatible with specific applications.

Packaging: Calcium carbonate powder is then packaged in bags or containers for distribution and use.

In addition to the above steps, calcium carbonate processing may also involve other processes, such as washing, drying, and calcining. The processing can be customized to meet specific production requirements, such as production capacity, powder fineness, and energy efficiency.

Overall, calcium carbonate processing is an important process for the production of high-quality calcium carbonate powder, which is used in a variety of industries, including paper, plastics, paints and coatings, and construction materials.
