China's phosphate rock distribution is highly concentrated, Sand Making Machine, the reserves of the prime 5 provinces are Yunnan, Guizhou, Hubei, respectively accounted for 24% of the reserves, 16%, 13%, 12% and 9%, and collectively accounting for 74%. Wealthy phosphorus ores (P2O5 grade is larger than 30%) are largely distributed in Yunnan, Guizhou, and Hubei province. On the surface China has lots of phosphate, but actually we are a bad phosphate country. The information showed that China's phosphate rock reserves and fundamental reserves have been four.one billion tons and 100 million tons, accounting for 27.14% and 21.28% of your international. Even so, we had much less large grade ore and a lot minimal grade ore, the common grade was only 17%. The high-grade ore with Phosphorus pentoxide is greater than 30% only accounted for only eight.5%; the cannot right use ores had been in excess of 90%. Phosphates as non-renewable assets are progressively depleted. America began to limit the export of phosphate rock and imported in substantial quantities as early because the 1980s. China has steadily recognized the significance of the phosphate rock resources.
The gurus point out the phosphate rock costs will grow up with the integration climax. 69% in the production of phosphate rock was used in the production of compound fertilizer, and higher efficiency and energy-saving Sand Making Machine is amongst the widely employed super fine grinding machines. It really is largely employed to grind elements in mineral, cement, refractory, chemical marketplace, and so on. Ball Mill has dry and moist techniques.
Since the phosphate rock assets are increasingly scarce, ball mill is handy to reduce the pollution and increase the resource utilization. Furthermore, crusher and other ore beneficiation equipments are all you finest and very first selection. Just about every connected tighten elements should be fixed tightly. Incorporating steel rod will depend on the fray case. If discovered the deviant problem, please end function and restore at as soon as. Adjust the liner of mill if it truly is frayed 70% or even the gash length reaches to 70mm. Adjust the bolt of liner if it really is destroyed,. Transform the key bearing if frayed heavily. Modify the fine-tooth comb if cannot be weld. In case the big gear wheel frayed heavily, turn it over to go on to use.16、Change the smaller gear wheel if frayed heavily. Fix it in time if your bolt of the feeder or output destroys, or modify it. If your foundation bolt is loosened or destroyed, please repair it at once.
