For minerals powder grinding, there are many grinding mills could be chosen, such as: Raymond mill, ball mill, vertical roller mill, ultra fine grinding mill and so on. Last week, part of our sales team went to Guangxi, China to visit our customer there, they are using our new technology CLUM vertical roller mill in the calcium carbonate powder making business. Let’s see, what our sales had seen there.
According our customer introduced, they had the largest calcium carbonate powder production base in vertical roller mill at domestic at present, their high quality calcium carbonate powder even can be exported to abroad more than 100 countries, because the caco3 powder had a widely use in various industries：
1.) Calcium Carbonate Powder Use in Paper: In the paper sector, micronized calcite has been used in paper and cardboard production by adding it into cellulose in different proportions. Since calcium carbonate increases the whiteness of paper, naturally.
2.) Calcium Carbonate Powder Use in Paint: The excellent whiteness of our carbonates avoids interference with the paints colors and contributes to their opacity and that the paint will cover, without dripping, the surfaces.
3.) Calcium Carbonate Powder Use in Plastic: Calcium carbonate mineral widely used as mineral fillers in order to obtain high humidity retention, to improve the consistency and dryness of the final mass. These polymers have various applications like in bags, pipes, automotive parts, furniture, containers etc.
4.) Calcium Carbonate in Cosmetics: Calcium carbonate is widely used in the cosmetics industry in make-up, soaps, toothpastes etc. Use of calcium carbonate imparts many benefits in making cosmetic products
5. ) Calcium Carbonate in Glass: Calcium carbonate powder for glass industry must compose of a high and consistent percentage of CaC03 and be devoid of color imparting impurities like Fe2O3 etc.
Above all are the calcium carbonate powder use in the other areas, but it’s the just some common use. Just because the calcium carbonate powder has so many different use, so there are more and more businessman devoted into the filed of calcium carbonate powder processing. The customer using our CLUM vertical roller mill to process the calcium carbonate powder, the higher efficiency can ensure they can supply more calcium carbonate powder for their customers.
Adding appropriate grinding aids during calcium carbonate powder grinding can greatly improve the vertical roller mill grinding efficiency and dispersion performance of grinding products. The grinding aid mainly improves the grinding process by changing the hardness of the material and the interaction between the particles.
The calcium carbonate powder can be successfully produced by vertical roller mill, whose fineness can meet the requirements of paper industry and painting industry. Rotation speed, feeding size and grinding aid are the main factors affecting the grinding efficiency of the vertical roller mill. In order to obtain high grinding efficiency, the grinding conditions should be strictly controlled.
