Use of phosphate fertilizer waste to produce gypsum powder
The country's largest new production line for the production of gypsum powder from the waste of phosphate fertilizers was built in Henan Nanle Huatai Chemical Building Material Co., Ltd., which created significant benefits. As of yesterday, the production line has produced more than 30,000 tons of qualified gypsum powder products. It is understood that this production line can not only eat up 300,000 tons of phosphate fertilizer residue (phosphogypsum) each year, but also reduce the cost and increase efficiency by 4 million yuan.
According to statistics, at present, about 20 million tons of phosphogypsum is produced in the country's phosphate fertilizer production, and the annual treatment capacity does not exceed 10%. A large number of accumulated phosphogypsum piles have become a major public pollution hazard. According to general manager Liu Shaowei of Huatai Company, the company is a chemical building material company that produces paper plasterboard. How to turn phosphogypsum into a treasure and achieve economic scale is what the company is pursuing. Phosphogypsum can not be directly used for the production of building materials without treatment. There are two reasons: First, phosphogypsum contains many harmful substances such as phosphorus, fluorine, and sulfur organic substances, which are used for building materials harmful to human body; Second, impurities exist in phosphogypsum. The solid strength of the produced gypsum powder combined with water is not enough, so it must be processed through a specific process. To this end, two years ago, Huatai Company invested 11 million yuan to adopt the national patented technology for desulfurized gypsum powder production process, and began to build a production line that uses gypsum plaster as raw material to produce gypsum powder and has an annual production capacity of 200,000 tons. The West Chemical Fertilizer Plant signed a supply and sales contract for phosphogypsum. After two years of hard work to succeed. The company uses phosphogypsum to produce gypsum powder production line is a national patent process, the gypsum powder produced without harmful substances, its physical properties and natural gypsum powder, can be directly produced building materials, reflecting the advantages of circular economy. It is estimated that one ton of phosphogypsum can produce 0.7 tons of gypsum powder. In this way, Huatai's gypsum powder production line can handle nearly 300,000 tons of phosphogypsum annually. The cost per metric ton of phosphogypsum is only 30 yuan, and it can add about 100 yuan after being processed into gypsum powder. Compared with the pure gypsum used as a raw material, 50 yuan per ton of gypsum powder can be saved. Only this one, the company can reduce the cost of 4 million yuan each year.
The reduction in the cost of raw materials has led to a further reduction in the production cost of the company's leading product, gypsum board, which has produced a benign chain effect.
