Gypsum Grinding process for gypsum powder making

The one-step process of crushing-screening-calcinations is mainly used in gypsum powder making for construction uses. The once completion of drying, Grinding, calcinations, screening, and modification can produce high grade calcined gypsum and other products with the lowest investment cost and powder consumption.

In gypsum powder production plant, the most important processes are drying, Grinding, calcinations and screening. The gypsum materials are grinded into gypsum powder of less than 80 meshes in size, and produce phosphogypsum by reaction with sulfuric acid replacement. However, the phosphogypsum material usually contains some phosphogypsum ores which are not grinded into powder, as well as some stone, coal grains, sand, mud and other impurities. So between drying and crushing processes, we specially add a “soft Grinding equipment” which grinds only gypsum lumps but not the impurities. After gypsum calcinations, the strong airflow blows the qualified gypsum powder to the following process, while the impurities are separated out of kiln. Therefore, the drying, Grinding, calcinations and screening processes are completed in one kiln. What's more, the temperature, time, air strength in the kiln can be easily controlled. The calcined gypsum powder is modified, homogenized, cooled and transported into storage.
