Such mills combine the grinding process with a drying one. Thus, no additional drying unit is required. All the above-mentioned equipment is manufactured by the Strommashina plant. The third stage is the earthy gypsum calcination. The gypsum binder production is classified into the following flow charts based on heat treatment types:

The pulverized Gypsum was calcined in a vessel of some type, likely ceramic. The resulting product, eventually many hundred of years later, named Plaster of Paris, provided this early man with a medium for making cast objects. In the grinding stage the fineness most generally is turned out at 90-93% minus 100 mesh with a 325 mesh range of 30 to ...

The dried desulfurized gypsum can be directly put into a continuous wok for frying. Compared with natural gypsum, the process and equipment such as jaw crushing, grinding and dust collection can be omitted, so the process is simple and the calcination cost is low. On the whole, it has a competitive advantage over natural building plaster.

Calcination temperature: ordinary gypsum powder calcination temperature 125~180 °C. Anhydrite is produced above 180 °C. Production Process And Main Equipment Of Building Gypsum. The construction gypsum made of natural gypsum must pass through the process of crushing→homogenization→milling→calcining.

Calcination follows these steps as a sort of finishing process, serving multiple purposes in bringing the finished catalyst to market. The primary reason for calcining the catalyst is to cure or "set" the actual catalyst material, typically a metal, onto the catalyst carrier or substrate, typically a ceramic-based material such as alumina .
