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.
