There are actually 3 most important solutions to classifying material: reselection, magnetic separation, flotation separation, electric variety, and chemical separation. In accordance to your physical and chemical properties of ores, the different methods of separation might be picked. The principle equipments are magnetic separator, Raymond mill, flotation machine, spiral chute, shaking table and and so on. Our organization will take scientific management process of present day enterprise manufactures superior quality solutions and persist steady innovation. Our principal equipments are crusher, sand maker, ore dressing equipments, ball mill, dryer, rotary kiln, pulverizer and etc. they are really widely used from the industries of mining, creating material, bridge, coal, chemical, millenary, and fireproofing resources.

China's phosphate Raymond mill distribution is highly concentrated, the reserves on the leading 5 provinces are Yunnan, Guizhou 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 mostly distributed in Yunnan, Guizhou, and Hubei province. About the surface China has lots of phosphate, but the truth is we are a poor phosphate country. The information showed that China's phosphate rock reserves and basic reserves had been four.1 billion tons and one hundred million tons, accounting for 27.14% and 21.28% of the international. However, we had less large grade ore and considerably minimal grade ore, the common grade was only 17%. The high-grade ore with Phosphorus pentoxide is higher than 30% only accounted for only 8.5%; the can't straight use ores have been a lot more than 90%. Phosphates as non-renewable resources are progressively depleted. America began to limit the export of phosphate rock and imported in substantial quantities as early since the 1980s. China has gradually realized the importance of the phosphate rock resources.

At existing, the grinding mill medium and smaller ore mining factories adopt two stages or three stages crushing circuit; the huge scale mining factories adopt 3 phases crushing circuit; some large scale mining factories adopt four stages open circuit crushing circuit because of the major raw materials block. Traditional crushing and screening equipments utilised by the ore mining factories are: jaw crusher, impact crusher, cone crusher and sand maker. Grinding and classifying. Within the ore mining plant, ore grinding follows ore crushing and steady crush and grind the ore. It is an important a part of beneficiation. The good quality in the grinded item directly has an effect on the concentration index. The ore grinding method consisted by grinding machine and classifier referred to as ore grinding classifying course of action, which can make the final product or service granularity fit the necessity of following procedure. Ore grinding course of action must be very simple, versatile, and also have selected adaptability. Principal equipments of ore grinding system are: ball mill, grid ball mill, wet type ball mill, Raymond mill, vibrating display, and spiral classifier.
