And with more than ten years of experience in powder equipment manufacturing and research and development, it has become a major powder equipment manufacturer and export base.

Phosphogypsum refers to the solid waste slag produced when Tassel Ang is used to treat phosphate rock in the process of phosphoric acid production. Its main component is calcium sulfate. The main component of phosphogypsum: CaSO4·2H2O, in addition to containing a variety of other impurities.

How to deal with phosphogypsum?

In addition to “in situ solution”, phosphogypsum is a way to bring greenery to the people. In recent years, the local environmental protection department has also explored some new ways to make phosphogypsum into gypsum powder that can be used comprehensively. At present, from a technical point of view, there are three main ways: one is to produce sulfuric acid and co-produce cement or calcium oxide; the other is to be used as a cement retarder; and the third is to produce new gypsum building materials.

Whether it is to make any of the above products, it requires the secondary crushing, grinding and mixing of powder and other processes. Dawn machine group is committed to the development of a vertical mill for phosphogypsum after nearly 30 years of research and development.Welcome to visit the factory at any time for more details.
