Nano calcium carbonate is best choice for paint & coatings industry. For this application and the fineness requirement, it is better to choose the small jaw crusher, Super Thin Mill, or Micro Powder Mill , their fineness can reach 625 to 3000 mesh. So the super fine powder can be the best products. Kefid can supply you with the best grinding mill, also can supply you with best grinding plant for processing calcium carbonate.

Nano calcium carbonate used in the coatings industry is the development of the industry in recent years, a major trend, so that the coating has a fine, uniform, quick-drying, optical properties and good. Relative to the common lithopone, there are stronger adsorption and surface chemical properties, so the surface tension of nano calcium carbonate coating is less than lithopone paint, while hiding the highly fragmented nature of it stronger than lithopone paint . Nano calcium carbonate filler coatings do, reduce the liquid cohesion, surface coating smooth, good texture.

Using fillers for paints and aggregate characteristics, special spindle nano calcium carbonate, relative to the common lithopone and titanium dioxide, the product particles are extremely small, completely wet with water, easy to grind and disperse, there is strong adsorption, its opacity in lithopone, smooth coating, colorful and texture, and can be expensive to replace a large number of titanium dioxide, while reducing the amount of adhesive binders, substantially lower costs, significant economic benefits . Nano calcium carbonate has been used successfully in many paint manufacturers to develop advanced nano-coating to improve the technological content of products.
