TSP is rich in mineral resources, almost the majority of the provinces across the country have TSP mineral distribution, multi-mineral, widely application, so a lot of businesses have been the target of production of heavy calcium. Heavy calcium carbonate is an important inorganic fillers which are widely used in the plastics, paper, rubber, paint, ink, cosmetic, food, feed, pharmaceutical and other industries. With the rapid development of the plastics industry, TSP demand becoming more and more, the forecast of heavy calcium instead of calcium light is the inevitable trend of development. The applications of heavy calcium is broad, but the technology requirements are relatively high, the general production applications must be reached between 800-2500 mesh, traditional stone grinderis very difficult to meet this requirement. In recent years, with the advancement of technology, SHANGHAI CLIRIK introduce the international advanced technology build heavy calcium ultrafine stone grinder, to solve modern milling process requirements, to ensure the production while improving product fineness.Ultrafine stone grinderwith wear-resistant materials, to solve the contradiction between stability and abrasion of the grinding body gradation to meet the requirements of ultra-fine grinding operation, stable production, high annual utilization, large scale; unit power consumption and compared to other stone grinder has greatly reduced, comprehensive technical indicators advanced, easy maintenance, and has good prospects for development.
