Heavy calcium carbonate powder (hereinafter referred to as heavy calcium) is a natural calcite, marble, dolomite or chalk as raw material, after grinding and classification of machinery and equipment reached a certain degree of fineness of the product. Will generally be less than 400 mesh product is classified as a meal, 400 -600 mesh called ordinary powder,600-800 mesh known as the fine mesh,800-1250 known as the ultra-fine powder, known as the 1250 Head ultrafine powder. Superfine heavy calcium carbonate is what we call after English Malvern or the United States Coulter laser particle size analyzer, D97 ≤ 17 um (800 mesh) heavy calcium.
2500 mesh products to dry production from 2500 to 6500 mesh-based wet process.2000, the international community has emerged dry production from 2500 to 6500 the purpose of the advanced heavy calcium grader equipment in 2003, China has been the introduction.
TSP dry processing equipment, grinding and grading equipment. Mature grinding equipment Raymond mill, impact mill, dry-type stirring mill, jet mill, vertical roller mill, vibrating mill and ball mill; grading equipment is mainly used to force the eddy current principle to manufacture the impeller ultrafine grading machine. Grinding equipment and grading machine with the composition of ultra-fine processing system, you can achieve the production of superfine heavy calcium powder. Comprehensive view of the various processes and equipment, generally can achieve the certain ultrafine effect. But what kind of production technology and equipment is more scientific and reasonable?
TSP production principles to achieve: the technology is mature, reliable equipment operation; tons of products with less investment, low energy consumption; investment at the same time yield the bigger the better.
