Light calcium powder, also known as light calcium carbonate, is produced by calcining raw materials such as limestone to produce lime, the main components of which are calcium oxide and carbon dioxide. The lime is then slaked with water to form lime milk, which is then carbonated by passing in carbon dioxide to produce a calcium carbonate precipitate. Finally, after dehydration and drying, it is pulverized by a lime pulverizer. Alternatively, it can be produced by a double decomposition reaction between sodium carbonate and calcium chloride to generate a calcium carbonate precipitate, followed by dehydration, drying, and pulverization. Because the sedimentation volume of light calcium powder (2.4-2.8 mL/g) is larger than that of heavy calcium powder (1.1-1.4 mL/g), it is called light calcium powder.

Applications of Light Calcium Powder: Light calcium powder is widely used in papermaking, plastics, plastic films, chemical fibers, rubber, adhesives, sealants, daily chemicals, cosmetics, building materials, coatings, paints, inks, putty, sealing wax, putty, felt packaging, medicine, food, and feed. Its functions include: increasing product volume, reducing costs, improving processing properties such as adjusting viscosity, rheological properties, and vulcanization properties; improving dimensional stability; reinforcing or semi-reinforcing; improving printing performance; and improving physical properties such as heat resistance, matting, wear resistance, flame retardancy, whiteness, and gloss.

Given its wide range of applications, light calcium powder naturally requires the assistance of milling equipment. A good pulverizer can ensure the quality of the light calcium powder. The manufacturer recommends using the HC series swing pulverizer for the production of light calcium powder. Traditionally, Raymond mills are used to produce light calcium powder; the HC series swing pulverizer is an upgraded version of the Raymond mill. The HC1700 and HC2000 super-large calcite pulverizers have high output and low energy consumption, making them particularly suitable for large-scale calcite powdering projects. These series of ore pulverizers can adjust their output between 1-25 tons per hour and their fineness between 0.18-0.015 (80-800 mesh). The HC series pulverizers operate smoothly, have a small footprint, low overall cost, high output, and uniform product particle size, making them very suitable for pulverizing light calcium.
