Introduction to the Industrial Use of Ultrafine Grinding Mill for Grinding Phosphogypsum

Phosphogypsum is a solid waste obtained from the treatment of phosphate ore with sulfuric acid when phosphoric acid is produced by fine grinding with phosphate ore and other ore raw materials. The main component of this solid waste is calcium sulfate. Apart from calcium sulfate, phosphogypsum also contains many other substances, such as apatite, phosphorus pentoxide eutectic, fluoride, sulfate and so on. These materials can be used for industrial purposes. Therefore, according to industrial needs, suitable grinding machine or ultrafine grinding mill can be selected for grinding processing, which can be used in arch industrial production.

In addition, phosphogypsum sometimes contains some radioactive elements. According to the above description, we found that phosphogypsum contains a lot of sulfur elements, and if these sulfur elements are collected, they can be used in the production of industrial sulfuric acid and other substances. And many users also found the economic value of phosphogypsum and began to use the special ultrafine grinding mill for phosphogypsum grinding production.

The processing and production of phosphogypsum generally include two links: ore crushing and phosphogypsum grinding. The ground phosphogypsum powder can be used in industrial production. So far, people generally choose jawbreaker, ultrafine grinding mill, and other processing and production equipment for phosphogypsum. The jaw crusher is mainly used for the crushing production of large pieces of phosphogypsum, and the crushed phosphogypsum is then transported to the ultrafine grinding mill for grinding, which can be used for grinding production.

After grinding to 3400 mesh size by ultrafine grinding mill, and then processing, it can be used in industrial production. According to the summary, the main industrial applications of ground phosphogypsum powder are as follows: using phosphogypsum to produce sulphuric acid cement, which uses sulfur element in phosphogypsum to produce cement, while other components are used for cement clinker. The cement buffer can be produced by mixing phosphogypsum powder and dihydrate gypsum in a certain proportion. Phosphogypsum powder is proportionally mixed with cement, fiber reinforced material and pulp, which can be used to make phosphogypsum fiberboard. In addition, phosphogypsum mixed with other raw materials can also produce crystal glass materials, gypsum bricks and so on. Finally, because phosphogypsum contains abundant calcium and sulfur elements, it can be processed by ultrafine grinding mill to produce ammonium sulfate, potassium sulfate, calcium sulfate, and other products.
