As an indispensable byproduct in the production of phosphate fertilizers, the production and utilization of phosphogypsum is not only related to the efficient circulation of resources, but also an important part of achieving green and sustainable development. This article will deeply discuss the introduction and production of phosphogypsum, the downstream application of ultrafine phosphogypsum powder, and the treatment process of phosphogypsum, and focus on the key role of 1000 mesh ultrafine phosphogypsum grinding machine in promoting this circular economy process.

Introduction and production of phosphogypsum

Phosphogypsum, with the chemical formula of CaSO4·2H2O, is a calcium sulfate mineral containing water of crystallization. It is mainly obtained in the process of phosphate fertilizer production through the reaction of sulfuric acid and phosphate rock. For every ton of phosphoric acid produced, about 4.5 to 5.5 tons of phosphogypsum are produced. With the continuous growth of global agricultural demand for phosphate fertilizers, the output of phosphogypsum has also surged. How to effectively handle and utilize this huge by-product has become a major issue facing the industry.

Downstream applications of ultrafine phosphogypsum powder

After scientific treatment, phosphogypsum, especially the ultrafine powder processed by 1000 mesh ultrafine phosphogypsum grinding machine, shows a wide range of application potential. On the one hand, ultrafine phosphogypsum powder can be used as a cement retarder to effectively improve cement performance and reduce production costs; on the other hand, it can also be used as a raw material for building materials, soil conditioners, and gypsum boards, and even in some high-end fields, such as fillers, coatings and plastic modification, it can also play its unique value. These applications not only broaden the utilization channels of phosphogypsum, but also provide new ideas for realizing resource recycling.

Phosphogypsum treatment process

The processing technology of phosphogypsum mainly includes purification and impurity removal, dehydration and drying, grinding and refining. Among them, grinding and refining is a key link, which is directly related to the quality and application range of phosphogypsum products. Traditional grinding equipment often cannot achieve the ideal fineness requirements, and has high energy consumption and low efficiency. The emergence of 1000 mesh ultrafine phosphogypsum grinding machine has completely changed this situation.

1000 mesh ultrafine phosphogypsum grinding machine introduction

Guilin Hongcheng 1000 mesh ultrafine phosphogypsum grinding machine HLMX series ultrafine vertical mill, with its high efficiency, energy saving and environmental protection, has become a star product in the field of phosphogypsum deep processing. The HLMX series ultrafine vertical mill is an upgraded and optimized product for ultrafine powder processing based on the coarse powder vertical mill, which can realize the large-scale production of ultrafine powder. The equipment has advanced grading technology and adopts multi-head rotor powder rotation to accurately control the particle size distribution and ensure the stability of phosphogypsum fine powder. The whole production line adopts PLC automatic control, which is simple to operate, convenient to maintain and low in labor cost.

As the core equipment in the phosphogypsum treatment process, Guilin Hongcheng 1000 mesh ultrafine phosphogypsum grinding machine not only promotes the transformation of phosphogypsum from waste to high-value resources, but also contributes to the construction of a resource-saving and environmentally friendly society.
