In mineralogy and geology, phosphate refers to a rock or ore containing phosphate ions. The largest phosphorite or rock phosphate deposits in North America. It is the major resource mined to produce phosphate fertilisers for the agriculture sector. Phosphate is also used in animal feed supplements, food preservatives, anti-corrosion agents, cosmetics, fungicides, ceramics, water treatment and metallurgy.
The separation of phosphate rock from impurities and nonphosphate materials for use in fertilizer manufacture consists of beneficiation, drying or calcining at some operations, and grinding. Rock phosphate particle is not the finished products, what we need is rock phosphate powder. Usually the powder is 100-800 mesh, 1250 mesh, and 4000 mesh. In order to get them, we need use rock phosphate grinding mill to grind rock phosphate particle into powder.
HGM micro powder mill is a new type and high efficiency phosphate rock grinding mill by absorbing the Swedish advanced machine manufacturing techniques. It is the grinding equipment used to process fine powder and super-fine powder. Product fineness can be controlled between 325~2500 mesh.
Spodumene: According to the hard rock crushing process, the crushed product is generally 5-40mm, combined with different design requirements of customers, two-end or three-stage crushing, high-grade crushed products (above 4-5%) can be directly used in the metallurgical process to produce lithium carbonate Or lithium hydroxide, the particle size of the finished product is generally around 20-40mm; low-grade generally requires ball mill grinding and separation, and the particle size of the finished product is generally around 5-20mm;
