Phosphogypsum Residue Grinding Mill/Phosphogypsum Micronizer/Phosphogypsum Powder Grinding Machine

The utilization of phosphogypsum residue is the bottleneck of high-quality development of phosphorus chemical industry. With the over exploitation of phosphate rock resources, phosphate rock resources may be exhausted in the next 30-100 years. The major countries of phosphate resources began to pay more attention to the strategic value of phosphogypsum residue, and issued relevant national policies to implement the protective development of phosphate resources.

Present situation of phosphogypsum residue treatment

Phosphate chemical industry broke out collectively, and phosphate products are still in a tight supply situation. Many enterprises focus on the reuse of phosphogypsum residue, facing the worldwide problem of phosphogypsum residue. In 2011, China explicitly issued a document to support the comprehensive utilization of industrial by-product phosphogypsum residue. Over the past 10 years, the comprehensive utilization rate of phosphogypsum residue has also increased. The data shows that the stock of phosphogypsum waste residue in China is gradually increasing.

Utilization of phosphogypsum residue to promote social and economic benefits

Based on the concept of solid waste recycling and building energy saving, the comprehensive application of phosphogypsum residue has the following values.

（1）Solid waste recycling, green and sustainable. Each consumption of 25-30 million cubic meters of phosphogypsum waste residue can liberate 1 square kilometer of land resources, which is conducive to the sustainable development of phosphorus chemical industry.

（2）High efficiency and money saving, high demand. The cost per cubic meter of phosphogypsum waste used as lightweight aggregate is about 101.7 yuan, which is far lower than that of crushed stone and shale ceramsite.

（3）Energy saving and emission reduction, meet the requirements of energy saving and green building, provide a cost-effective and energy-saving product for building materials industry.

Phosphogypsum residue grinding mill of HCM

HCMilling (Guilin Hongcheng) has been focusing on the research and development of solid waste grinding equipment, with the spirit of continuous improvement of craftsmanship and excellent special solid waste grinding equipment. It can promote the transformation of solid waste residue into treasure, help the solid waste residue field such as phosphogypsum residue to embark on the new industrial recycling development road, and supply special mill equipment and complete grinding solution for solid waste residue recycling development project.

HLM vertical roller mill machine is a grinding equipment developed by HCM team after 20 years. It solves the problems of low output, high energy consumption and high maintenance cost of ordinary industrial mill, and the product performance reaches the international leading level. It is confirmed by the new and old customers and the market in solid waste treatment. The water content of the feed should reach 15% at most, which can meet the requirements of drying and grinding of materials with different humidity, and the solid waste powder such as phosphogypsum waste residue is the best choice.

HLM series vertical roller mill：

     *Disc diameter*：1000-52400mm

　　*Moisture content of feed material*：≤5%

　　*Capacity *：4-40t/h

*Product fineness*：10-45 μ The secondary classification of m-match can reach 5 μ m

*Application filed*：It is widely used in papermaking, coating, plastics, rubber, pigment, ink, PVC and other fields of production and life.

*Applicable materials*：It has high capacity and high efficiency for grinding of various nonmetallic mineral materials with Morse hardness below 7 and humidity less than 6%. For example, limestone, calcite, marble, heavy calcium, kaolin, barite, bentonite, pyrophyllite and other grinding effects are good.
