Grinding Mill For Heavy Calcium Preparation

Summary of contents: The heavy calcium powder after being ground by a grinding mill can be used for food additives when its particle size distribution is controlled at 4-16 microns; it can be used for paints with good whiteness, fine particle size distribution and low abrasiveness. An extender to improve opacity, mattness, crack resistance and corrosion resistance; a particle size of 50-75 microns, a good whiteness of heavy calcium powder can be used for paper fillers, thereby increasing the whiteness of the paper, Printability, high loadability and dewatering, mainly used for uncoated and woodless paper.

Heavy calcium, that is, heavy calcium carbonate, is a calcium carbonate powder produced by crushing a grinding mill using ore such as calcite, chalk, and marble. Heavy calcium carbonate is an inorganic non-metallic mineral powder product with rapid growth in production in the past 20 years. At present, the national production capacity has reached about 20 million tons/year. China has become a major producer and application of heavy calcium carbonate in global production for nearly 10 years. Come, China's heavy calcium carbonate production has achieved an average annual rate of 10%. Heavy calcium is essential in many areas and plays an important role. The following figure reveals its important uses.

The heavy calcium powder after being ground by the grinding mill can be used for food additives when its particle size distribution is controlled at 4-16 microns; the whiteness is good, the particle size distribution is fine, and the abrasiveness is low, which can be used for the extension in paint coatings. To improve opacity, mattness, crack resistance and corrosion resistance; particle size 50-75 microns distribution, good whiteness of heavy calcium powder can be used for paper filler, thereby improving paper whiteness, printability, High loadability and dewatering, mainly used for uncoated, woodless paper. As shown in the above figure, in addition to these uses, heavy calcium powder can also be used in the fields of plastic pipes, cables, artificial leather and the like. In the future, the large-scale and intelligent production of grinding mill heavy calcium production line, product functionalization (fineness and activation) and product quality stabilization have become the main development trend of heavy calcium carbonate industry.
