Calcium carbonate is widely used in Papermaking industry, it is used as filler. Kefid calcium carbonate crusher and calcium carbonate grinding mill can processing the calcium carbonate to the suitable size or fineness, then the calcium carbonate can be used as the filler in Papermaking. Here we recommend you the calcium carbonate High Pressure Mill and the calcium carbonate Vertical Mill, if need the price, please chat online.

Calcium carbonate in papermaking mainly for filler paper, in order to ensure a certain strength of paper, whiteness, while reducing costs, adding a lot of calcium carbonate in the paper. Paper industry is based on extensive use of calcium carbonate from the international paper industry turning acidic alkaline or neutral papermaking process causing paper craft, so you can use a large number of inexpensive calcium carbonate talc and clay instead of the past. Light calcium carbonate as a filler for paper, has several advantages over kaolin and FGCC.
1, with a high opacity and gloss.
2, as a filler, an increase of high capacity.
3, uniform particle size.
4, the color remains strong.

The paper can be improved by adding calcium carbonate opacity and brightness of paper, improving smoothness and uniformity of the state of paper, to increase the softness of the paper, reducing the moisture absorption and deformation of the paper, to improve the printing of the ink absorption performance, increase retention.

Specialty products for coating paper with a color white, high gloss, transparency, small, large refractive index, scattering coefficient, opacity characteristics, especially for recording paper thin pages printing paper, coated paper high whiteness the manufacture of paper and other high.

Calcium carbonate is a compound, Calcium carbonate is a raw material commonly used in the industrial production, the use of calcium carbonate in industry is mainly manifested in the following industries, such as the PVC industry,rubber industry, plastics industry, it can be used as additives in the smelting industry. According to the type of calcium carbonate production process, can be divided into calcium carbonate, heavy calcium carbonate, light calcium carbonate, colloidal calcium carbonate, and crystal calcium carbonate.

Calcium carbonate process flow

The raw of Calcium carbonate mineral materials enter the crusher for primary crushing,the calcium carbonate fragments are elevated to the grinding machine host, the analysis machine selected to meet the requirements of the micronized, the powder collector collect the fine powder,pulse dust filter dust.The calcium carbonate production process is very simple,grinding calcium carbonate is the main part of ,the choice of the milling equipment directly determines the status of the production of calcium carbonate in the entire production line, but also determines the quality of the finished product of calcium carbonate powder.

Calcium carbonate mill equipment performance

Calcium carbonate milling equipment to determine the performance under the following conditions：
1.After being processed by calcium carbonate griding equipment ,whether  the calcium carbonate micro powder can reach the fineness requirement .
2.Calcium carbonate milling equipment is easy to operate and maintain
3.Production can meet the needs of the calcium carbonate processing equipment unit time.
4.Calcium carbonate milling equipment must also meet the needs of environmental protection.
