It can be prepared by directly crushing natural calcite, limestone, chalk, shell, etc. by mechanical methods (using Raymond mill or other high-pressure mill). Because the sedimentation volume of heavy Calcium Carbonate is smaller than that of light calcium carbonate, it is called heavy calcium carbonate.
Heavy calcium carbonate is abbreviated as heavy calcium. It uses high-quality limestone as raw material and is processed into white powder by a lime mill. Its main component is CaCO3. Heavy calcium has the characteristics of high whiteness, good purity, soft hue and stable chemical composition. Heavy calcium is usually used as a filler. It is widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, construction supplies, food, medicine, textiles, feed, toothpaste, etc. Increase the volume of products and reduce production costs. Used in rubber, it can increase the volume of the rubber, improve the processability of the rubber, play a semi-reinforcing or reinforcing role, and can adjust the hardness of the rubber.

Liaoning Panjin Marine Engineering Equipment Manufacturing Base is located in the Panjin Liao-Bin Economic Zone, with a planned area of ​​23.7 square kilometers, which is suitable for the development of offshore engineering equipment manufacturing shoreline up to 21.5 kilometers. The base will develop the marine engineering equipment industry in the fields of offshore oil drilling platforms, drilling machinery, oil extraction equipment, and offshore wind power equipment based on the rich oil and gas, shoreline, port resources, and petroleum equipment industry bases. At present, the base is in the stage of infrastructure construction and investment attraction. There have been a number of companies such as China National Offshore Oil Equipment Factory and Liaoning Hongguan Shipyard Co.
Recently, the Liaoning Science and Technology Department and the Panjin Municipal Government jointly invited 11 well-known experts in the fields of domestic shipbuilding, oil drilling, and wind energy development to Shen to build a “pulse†for the Liaoning Panjin Marine Engineering Equipment Manufacturing Base. In the next three to five years, Panjin, Liaoning Province, will develop a special industrial cluster with a scale of 100 billion yuan in marine engineering equipment.
