Right now, technological innovation has become the main engine for the development of the calcium industry in Nanzhao. Nanzhao County established 3 provincial R&D centers, a provincial-level testing center, and 4 municipal R&D centers around the non-metallic new materials industry. The company’s R&D capabilities have been continuously enhanced, production technologies have been continuously innovated, and product quality has been greatly improved. In particular, through technological innovations, some enterprises in the county processed solid wastes such as slag and corner wastes into desulfurizers that are widely used by power plants and cement plants, raymond mill. Or used as a filler for other new materials to ensure the comprehensive benefits of raw materials.
With the extensive and in-depth application of high quality industrial heavy calcium carbonate in plastics, rubber, papermaking, building materials, and chemical industries, the county fully grasps the opportunities of industrial transfer in developed regions and focuses on the introduction of new building decorative materials and packaging materials. The calcium carbonate middle and downstream enterprises that have large investment scales, strong technical strength, and high added value products will develop high-end products, enhance the market competitiveness of new environmentally-friendly products, and achieve the goal of “Central China Calcium Capital”. Raymond Mill
According to the survey, in Nanzhao County, the total reserves of calcite resources used to produce heavy calcium carbonate amounted to 1 billion tons, ranking the top in the country. At present, the county's annual ore mining capacity reaches 2 million tons, and Raymond Mill can be exploited for 300 years, especially at this speed. Through technological innovation Raymond Mill, the quality of ore is excellent, and calcium carbonate content and whiteness are among the highest in the country. Nanzhao has abundant resources, large quantity and high quality, and has laid a solid foundation for Nanzhao to build “China Calcium Capital”.
