China's phosphate rock distribution is highly concentrated, the reserves of the top five provinces are Yunnan, Guizhou, Hubei, Hunan and Sichuan, respectively accounted for 24% of the reserves, 16%, 13%, 12% and 9%, and together accounting for 74%. Rich phosphorus ores (P2O5 grade is higher than 30%) are mainly distributed in Yunnan, Guizhou, and Hubei province. On the surface China has plenty of phosphate, but in fact we are a poor phosphate country. The data showed that China's phosphate rock reserves and basic reserves were 4.1 billion tons and 100 million tons, accounting for 27.14% and 21.28% of the global. However, we had less high grade ore and much low grade ore, the average grade was only 17%. The high-grade ore with Phosphorus pentoxide is greater than 30% only accounted for only 8.5%; the can not directly use ores were more than 90%. Phosphates as non-renewable resources are gradually depleted. The United States began to limit the export of phosphate rock and imported in large quantities as early as the 1980s. China has gradually realized the importance of the phosphate rock resources.
The experts point out the phosphate rock prices will grow up with the integration climax. 69% of the production of phosphate rock was used in the production of compound fertilizer, and Hongxing high efficiency and energy-saving ball mill is one of the widely used super fine grinding machines. It is mainly used to grind materials in mineral, cement, refractory, chemical industry, etc. Ball Mill has dry and wet ways.
As the phosphate rock resources are increasingly scarce, Hongxing ball mill is helpful to reduce the pollution and improve the resource utilization. In addition, Hongxing crusher and other ore beneficiation equipments are all you best and first choice.
