A calcium carbonate manufacturer introduces that calcium carbonate is classified into four types based on differences in particle size after crushing.

According to the differences in particle size after crushing, calcium carbonate manufacturers classify industrial-grade calcium carbonate into four distinct specifications: “Li Dui,” “Shuang Fei,” “San Fei,” and “Si Fei,” each tailored for specific industrial sectors.
According to the particle size after crushing, calcium carbonate manufacturers classify industrial-grade calcium carbonate into four different specifications: “Li Dui,” “Shuang Fei,” “San Fei,” and “Si Fei,” each of which is used in specific industrial sectors.
Off-site powder: Used for the production of anhydrous sodium sulfate (CaCl₂) and serves as an auxiliary raw material in the manufacture of sodium dichromate.
Double-fly ash: It is used as a white filler in raw materials such as anhydrous sodium sulfate and glass, as well as in plastics and paints, and in architectural decorative materials.
Three-Flight Powder: Used as a filler in plastics, architectural coating putties, architectural coatings, engineered wood panels, and paints.
Four-fly powder: used as a filler for wire insulation, molded rubber products, and asphalt-coated polypropylene fabric.
Conventional silane coupling agents, grinding aids, and thickeners struggle to enhance the specialized application performance and scope of heavy calcium carbonate powder. By “specialization,” we mean systematic research and development tailored to market-driven calcium carbonate specifications, enabling direct encapsulation and mutual affinity with specific high-value raw materials to meet the unique functional requirements and production demands of each. In doing so, the commercial value of high-quality calcium carbonate is significantly elevated.
In China, high-quality calcite deposits are widely distributed; however, many calcite producers merely engage in simple crushing and grinding, resulting in low selling prices, significant resource waste, low production output, and limited application scope.
However, after reprocessing with calcium carbonate as a grinding aid, the powder exhibits dramatically improved flowability, reduced oil absorption, and lower viscosity, leading to enhanced machinability. Moreover, the surface of the powder particles develops greater affinity and compatibility with high-grade raw materials, thereby expanding the range of application industries and better meeting the diverse needs of the market, ultimately boosting economic returns. This is particularly beneficial for enterprises dealing with low-grade ores and relatively outdated production processes.
Calcium carbonate manufacturers have developed specialized formulations for high-quality calcium carbonate, barite powder, light calcium carbonate powder, kaolin, and other powdered materials, significantly enhancing their performance. These formulations can reduce oil absorption, prevent agglomeration, provide antistatic properties, and increase production efficiency, while also being customizable to meet specific standards.
Product Features: This specialty calcium carbonate for artificial marble is produced by using ultrafine ordinary calcium carbonate as the raw material, incorporating a unique ester-based surfactant, and subjecting the product to surface treatment in accordance with surfactant-based surface-modification principles. It boasts low oil absorption and excellent long-term dispersion and anti-settling performance in polyurethane resin systems.
Application industry: Used in the artificial quartz stone sector.
Main function: In the production process of engineered quartz, the oil absorption value of the specialized filler for engineered quartz is very low. Compared with ordinary calcium carbonate powder, its addition ratio can be significantly increased, thereby reducing the amount of polyurethane resin used and lowering product costs.
