grinding process for gypsum Bruijn-counseling

The calcined gypsum is charged into the mill, heated to 280 F. by admission of steam into the grinding compartment, after which the process is identical to that used for uncalcined gypsum. When using calcined ypsum of large particle size, it is desirable to do most of the grinding before the mill as vented.
