With the rapid development of Chinese plastics, rubber, paper, architectural coatings and daily chemical industry, the demand for nano-calcium carbonate is increasing. raymond grinding mill is the main equipment for the processing of nano-calcium carbonate at this stage.
Nano-calcium carbonate is a new type of ultra-fine inorganic material developed in the 1980s. Due to the ultrafine refinement of the particles, the crystal structure and surface electronic structure are changed, and the effect that ordinary calcium carbonate does not have is produced. It is used as a plastic filler, and the tensile strength and elongation at break of the product are not greatly reduced due to the increase of the filling amount; the high proportion of the product is filled in the rubber, so that the surface of the product is bright and the rigidity is enhanced. It has improved tear resistance, bending resistance and crack resistance; it can be added to advanced inks and coatings to significantly improve the gloss, transparency and stability of the product; as a paper filler, it can greatly improve the whiteness, astigmatism and shadow of paper, reduce the amount of pulp.
The wide application of nano-scale calcium carbonate, Raymond grinding mill is indispensable. Guilin Hengda Mining Machinery Co., Ltd is a professional manufacturer engaged in the R&D and production of raymond grinding mill. The company’s HD series high efficiency low energy consumption raymond grinding mill is a hot-selling product. The specific parameters are as follows: Shown as follows:
