Phosphate ores are mainly produced in sedimentary rocks, metamorphic rocks and igneous rocks. Except for individual cases, phosphorus in minerals always exists in the form of orthophosphate, and the main mineral of phosphorus is apatite.
Phosphate rock is an important chemical mineral raw material, with many varieties. There are several more important ones ,such as phosphate rock powder, superphosphate, phosphorus nitrogen compound fertilizer, phosphorus nitrogen potassium mixed fertilizer, calcium magnesium phosphate fertilizer, etc. Some of them are used for extracting yellow phosphorus, red phosphorus, phosphoric acid and manufacturing objectively existing phosphates and phosphides.
It has important applications in agriculture, medicine, matches, dyes, sugar, food, textiles, glass, ceramics, and defense industries. Phosphorus is an important chemical raw material and an essential element for crop growth. Phosphorus for industrial use must be extracted from phosphate rock in large quantities for manufacturing yellow phosphorus, red phosphorus, phosphoric acid, phosphate fertilizer and phosphate.
Beneficiation process of phosphate ore: following the direct flotation process, the beneficiation and enrichment processes such as roasting and digestion, scrubbing and desliming, flotation and heavy medium of sedimentary phosphate rock have been developed successively. Among these technologies, direct flotation, reverse flotation, scrubbing desliming and heavy medium separation have been successfully applied.
At present, the scale of phosphorus ore processing and production is becoming larger and larger. The mining methods of phosphorus ore are divided into underground mining and open-pit mining, and most of them are mainly underground mining. The mining methods are mainly open stoping and caving. The equipment used in the mining of phosphate rock includes crushers, grinders, etc. The phosphate rock grinding equipment has a broad prospect.
SMMVIK Machinery, a Raymond mill manufacturer, specializes in the crushing and grinding of phosphate rock, and has achieved a great breakthrough in the production and processing of phosphate rock grinders. The transmission device of the main machine of the phosphate rock mill adopts a closed gear box, and the transmission is stable. The important parts of the mill are made of steel.
The whole machine is a vertical structure with small floor area and strong completeness. This series of grinding equipment has no pollution to the environment, and its function, efficiency, output and fineness have been improved. It is a good choice for processing phosphorus ore.
For the main application fields of phosphate rock, LUM superfine vertical mill, MTW European version mill, Raymond mill and other products produced by SMMVIK Machinery can be adjusted from 30 mesh to 425 mesh, which is a better choice for phosphate rock grinding.
