                                         The main purpose of the phosphorus gypsum

Phosphorus gypsum yield large, widely used, so the effective recycle more and more be taken seriously. Using customized powder grinding production line, the phosphogypsum can be treated to the thickness, different level to meet the needs of further processed.

(1) system combined sulfate cement

Phosphorus gypsum to make sulphuric acid combined this technology the sulfur composition of phosphorus gypsum cement regeneration for sulfuric acid, cement clinker due to other components.

(2) for cement retarder

Phosphogypsum can be single or double mixed in certain proportion and dihydrate gypsum used as cement retarder, double mixing effect is better. The performance of cement and add natural gypsum, and adding quantity is lower than natural gypsum, can reduce the cement production cost.

(3) the production of phosphorus gypsum building materials

Phosphogypsum and a small amount of cement, fiber reinforced material, such as pulp pressurized can be made into phosphorus gypsum fiberboard. Phosphogypsum and yellow phosphorus slag, fluorite, pigments and other ingredients can be made into color ceramic decorative materials; Phosphogypsum and copper flotation waste residue can be made into glass and crystal materials; Phosphorus gypsum and cement, sand can be made of high strength gypsum brick, etc.

(4) the production of chemical raw materials

Phosphogypsum is rich in calcium, sulfur resources, so you can make through a certain production process of calcium, sulfur resources transition. At present, the phosphorus gypsum is used for the production of ammonium sulfate, potassium sulfate, calcium carbonate, thiourea, etc.
