The HLMX1800 HCM ultra-fine grinding mill produces calcium carbonate powder at a rate of 25 tons per hour
The HCM grinding mill project for producing ultra-fine calcium carbonate powder is progressing smoothly. The project uses the HCM grinding mill HLMX1800 ultra-fine vertical mill to grind calcium carbonate to 35μm, with a production capacity of 16-25t/h, meeting the client's requirements. The particle size of the feed material for the HLMX1800 ultra-fine vertical mill is<10mm, with moisture content ≤5%. The fineness of the finished product is 5-22um (with a secondary classification system for 3-5um), and the production capacity is 9-22t/h, with a main unit power of 450KW. According to available information, by the end of 2024, the global total annual production capacity of ultra-fine active calcium carbonate is approximately 21.8 million tons. Among them, China leads with a production capacity of 9.8 million tons, accounting for 45% of the global total. The United States ranks second with an annual production capacity of approximately 2.8 million tons, accounting for 12.8%. Germany has a production capacity of approximately 1.85 million tons, accounting for 8.5%. Japan has a production capacity of approximately 1.3 million tons, accounting for 5.9%. India has developed rapidly in recent years, with its production capacity rising to approximately 1.1 million tons, accounting for 5.0%.
Global ultra-fine calcium carbonate technology is undergoing a transition from "scale-driven" to a dual-wheel drive of "performance + green". In terms of particle size control, the European and American markets generally require D50 particle size to be controlled within 0.08-0.15μm, specific surface area ≥25 m²/g, and pH value stabilized between 9.0-10.0. China enterprises have broken through key surface modification technologies, achieving stable particle size control within the range of 0.5-3μm, whiteness improvement to over 95%, activation degree exceeding 92%, and performance indicators reaching international advanced levels.
In the processing technology of calcium carbonate, grinding is a very important process and a key technology for particle size control. HCM grinding machine is one of the manufacturers of calcium carbonate grinding machines with strong capabilities, reliable quality, and comprehensive services. The HC series Raymond mills, HLM series vertical mills, HLMX series ultra-fine mills, and HCH series ring roller mills developed and produced by HCM grinding machine can produce calcium carbonate powder with particle sizes ranging from 3μm to 180μm. They can produce calcium carbonate powder of different fineness according to the requirements of industries such as plastics, coatings, paints, papermaking, rubber, pharmaceutical additives, food additives, adhesives, sealants, and feed. HCM grinding machine has high grinding and screening efficiency, adopts a PLC fully automatic control system with high automation, and uses special materials for grinding rollers and grinding plate liners, ensuring long service life.
