Phosphogypsum is a kind of solid waste produced during the production of wet process phosphoric acid. The reasonable utilization of phosphogypsum can reduce the waste of resources and realize the sustainable development of resources. The main components of apatite include calcium sulfate dihydrate, phosphate ore, residual phosphoric acid, fluoride, acid insoluble matter, organic matter, etc.

In the process of processing apatite into powder, LM vertical mill is a common powder making equipment. LM vertical mill is an advanced equipment which integrates crushing, drying, grinding, classifying and conveying. It has the advantages of simple process flow, compact structure, small footprint and high degree of automation. In addition, it adopts fully closed system and full negative pressure operation, no dust overflow, energy saving and environmental protection.The phosphatic limestone powder produced by LM vertical mill has uniform particle size, good fluidity and adaptability, which can improve production efficiency and product quality.

Apatite powder has a wide range of applications. The following are some common applications:

Sulfuric acid and cement raw materials: Apatite powder can be used as raw materials for the production of sulfuric acid and cement. By mixing apatite powder with other raw materials through suitable process treatment, high quality sulfuric acid and cement can be produced to meet the needs of industrial production.

Cement retarder: Apatite powder mixed with gypsum dihydrate can be used as a retarder for cement. The properties of this mixture are basically the same as those of natural gypsum, which can effectively control the setting speed of cement and improve the process performance of cement.

Chemical raw materials: Since phosphogypsum is rich in calcium and sulfide, it can be used as chemical raw materials after proper processing. These chemical raw materials can be widely used in the chemical industry for the production of various chemical products.

Through the rational use of apatite, we can realize the resourceful use of waste and reduce the dependence on natural resources while promoting sustainable development. The processing and application of apatite brings a variety of viable options for industrial production and chemistry, promoting the recycling of resources and environmental protection.
