Description ：

Phosphogypsum refers to the gypsum formed as a by-product of the production of fertilizer from phosphate rock. It is mainly composed of gypsum (CaSO4·2H2O).

After the phosphogypsum is treated with our production line, it can be used as construction gypsum and agricultural gypsum. 

Technology of phosphogypsum treatment:  Two-step treatment.  The first step is to remove the free water in the phosphogypsum raw material(the process is also called preheating).  Hot air and phosphogypsum raw material is mixed during going through hot air tube.  The second step is to remove part of the crystal water in the preheated   phosphogypsum. 

The phosphogypsum production line is composed of  hot air furnace,  preheating  system, calcining system, dust collecting system, modifying system, conveying system, packing system and storage system. 

Working Process of the Production Line

The basic process of making gypsum powder is:  phosphogypsum raw material —— preheating —— calcining —— dust collecting —— pin mill modifying —— silo—— packing machine
