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, after grinding or milling, can be used in the rubber products industry as additive. For this use, here we recommend our calcium carbonate grinding mill : calcium carbonate ball mill, calcium carbonate vertical mill, calcium carbonate micro powder mill. The fineness of which is 50-850 mesh, which can meet most of apllication.

Calcium carbonate having a fine, ultrapure characteristics, the production process can be effectively controlled crystal grain size and, after the surface modification treatment, the calcium carbonate has good compatibility with the rubber, and thus used in the rubber showing a three-dimensional structure in space, fundamentally changed the performance of rubber products. The rubber industry in developed countries, small seal, auto parts, ranging from tires, plastic and other industries has long been widely used calcium carbonate, it not only can be used as a reinforcing filler used alone, but according to production needs in conjunction with other fillers , such as: carbon black, light calcium or heavy calcium carbonate, kaolin, titanium dioxide, etc., to reinforcing, filling, color, processing technology and products to improve performance, reduce or replace part containing gum titanium dioxide, carbon black and other expensive white the purpose of the white filler.

Acicular calcium carbonate having a larger reinforcement in natural rubber and synthetic rubber, in use, make products elongation, tensile strength, tear strength, which are essential to improve, compared with ordinary light calcium carbonate filling amount increased by 50% above, improve the market competitiveness of these products.
