Development of the calcium carbonate industry. The calcium carbonate industry is a traditional industry in China. Because calcium carbonate is not difficult to find in nature, and the long-term market demand in the past was mainly for low-value white powder materials, the product upgrading of the domestic calcium carbonate industry has been slow, and it has mainly produced low-end products for a long time. With the country's vigorous promotion of industrial structure adjustment and energy conservation and emission reduction, the ultra-fine calcium carbonate industry in Guangdong, China, has undergone large-scale transformation and upgrading.

　Development of the Calcium Carbonate Industry. The calcium carbonate industry is a traditional industry in China. Because calcium carbonate is not difficult to find in nature, and the long-term market demand in the past was mainly for low-value white powder materials, the product upgrading of the domestic calcium carbonate industry has been slow, and it has mainly produced low-end products for a long time. With the country's vigorous promotion of industrial restructuring and energy conservation and emission reduction, the ultra-fine calcium carbonate industry in Guangdong, China, has undergone large-scale transformation and upgrading. At present, the lime calcination of enterprises has gradually been automated; lime digestion has developed from single-return ashing to trough ashing and wheel ashing; drying technology has developed from heat transfer oil tube drying to rotary tube drying, rotary steam drying, and disc drying; and carbonation technology has developed from single high-tower bubbling carbonation and low-tower bubbling carbonation to large-diameter high-tower carbonation.

 

 

　　In recent years, Guangxi Longhua New Materials has made great progress in production technology and equipment. Technological advancements have also led to product upgrades. Low-carbon and energy-saving nanotechnology has become a new engine for the development of the calcium carbonate industry, and high-tech, high-end, and environmentally friendly products have become the production goals of various enterprises. A new development trend emerging in the global ordinary calcium carbonate industry is that various special calcium carbonates are produced and form a satellite-type industrial structure with their downstream major users: papermaking and coating plants. Production near these major users allows calcium carbonate to be transported in slurry form via pipelines, eliminating the drying process for calcium carbonate slurry, saving a large amount of energy, and significantly reducing production costs. The domestic calcium carbonate industry has noticed this international development trend, and Guangxi Longhua New Materials has begun to actively contact downstream major users to explore the feasibility of building factories nearby and supplying slurry materials.
