Understand the production process of ground calcium carbonate
What is calcium carbonate?
Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and it is the main component of pearls and the shells of marine organisms, snails, and eggs. Calcium carbonate is the active ingredient in agricultural lime and is created when calcium ions in hard water react with carbonate ions to create limescale. It can also be precipitated by mixing calcium chloride and sodium carbonate.
What are the different types of calcium carbonate?
There are three different types of calcium carbonate: fine, medium, and coarse. Fine calcium carbonate is used in cosmetics and pharmaceuticals, while medium and coarse grades are used in construction materials like concrete and asphalt. Each type has different particle sizes, with fine calcium carbonate having the smallest particles and coarse calcium carbonate having the largest.
How do I know which type of calcium carbonate to take?
There are three main types of calcium carbonate: fine, medium, and coarse. The best way to determine which one is right for you is to consult with your doctor or a registered dietitian. They will be able to advise you on which type of calcium carbonate will best meet your needs.
Introduction to calcium carbonate
Calcium carbonate is a white, insoluble solid that occurs naturally in many rocks and minerals. It has a wide range of uses, including as a building material and an agricultural lime. It is also a key component in the manufacturing of paper, plastics, and cement.
The main types of calcium carbonate are:
Ground calcium carbonate (GCC) – This is produced by grinding limestone or marble into a powder. It’s used as a filler in papers, plastics, and paints.
Precipitated calcium carbonate (PCC) – This is produced by combining calcium oxide with water. It’s used as a filler in papers and as an absorbent in products such as diapers and cat litter.
Heavy calcium carbonate (HCC) – This is produced by crushing limestone into a powder. It’s used as an aggregate in concrete and asphalt, and as a weighting agent in drilling fluids.
The different mesh sizes of calcium carbonate
The different mesh sizes of calcium carbonate are: coarse, medium, and fine. The coarse mesh size is the largest and is used for the most abrasive applications. The medium mesh size is smaller and is used for less abrasive applications. The fine mesh size is the smallest and is used for the most delicate applications.
How to choose the right mesh size for your needs
There are a few things to consider when choosing the right mesh size for your needs. The first is the particle size of the calcium carbonate. If you need a very fine powder, you will want to choose a smaller mesh size. The second is the coarseness of the calcium carbonate. If you need a coarse powder, you will want to choose a larger mesh size. The third is the desired particle size distribution. You will want to choose a mesh size that will give you the distribution that you need. Finally, you should consider the production rate. A higher production rate may require a larger mesh size to achieve the desired particle size distribution.
Conclusion
If you need to purchase calcium carbonate, it's important to know the mesh size of the powder you're buying. The mesh size is a measure of how finely powdered the calcium carbonate is, and it can range from coarse to fine. Coarsely ground calcium carbonate is typically used for agricultural purposes, while finer powders are generally used in manufacturing or industrial applications. You can use this chart as a guide to help you choose the right mesh size for your needs.
