Calcium carbonate production equipment/calcium carbonate processing process flow

Calcium carbonate (chemical formula CaCO3) is a common inorganic compound widely present in nature, such as aragonite, calcite, chalk, limestone, marble, limestone, and other rocks. It is also the main component of animal bones or shells. Calcium carbonate has important industrial application value and is commonly used in the production of building materials, coatings, plastics, rubber, etc.

The production equipment and processing process of calcium carbonate are as follows:

1. Mining: Mining is carried out from mines rich in calcium carbonate, usually using methods such as explosive blasting or mechanical mining.

2. Crushing: Crush the extracted calcium carbonate ore to a certain particle size. Crushing equipment includes jaw crushers, cone crushers, impact crushers, etc.

3. Grinding: Grind the crushed calcium carbonate ore to improve its fineness. Grinding equipment includes ball mills, Raymond mills, etc.

4. Grading: The ground calcium carbonate powder needs to be graded to meet different fineness requirements. The grading equipment includes grading screens, air flow classifiers, etc.

5. Surface treatment: In order to improve the surface performance of calcium carbonate, such as increasing its hydrophilicity or hydrophobicity, surface treatment can be carried out. Surface treatment methods include surfactant modification, silane modification, etc.

6. Mixing: Mix the processed calcium carbonate with other additives such as resins, pigments, etc. according to production needs.

7. Forming: The mixture is formed by extrusion, rolling, and other methods, such as making plates, pipes, etc.

8. Drying: Dry the formed calcium carbonate product to reduce moisture content. Drying equipment includes ovens, drying rooms, etc.

9. Calcination: In order to improve the purity and activity of calcium carbonate, calcination treatment can be carried out. The calcination equipment includes rotary kilns, vertical mills, etc.

10 Crushing: The calcined calcium carbonate is crushed to meet the particle size requirements of different application fields. The crushing equipment includes impact crusher, airflow crusher, etc.

11 Packaging: Pack the crushed calcium carbonate product for easy storage and transportation.

The above is the production equipment and processing process of calcium carbonate. In actual production, adjustments and optimizations may be made based on product usage and requirements.
