Hemihydrate an overview ScienceDirect Topics

In these mills, hot gas contacts gypsum. It dries and calcines the gypsum and then conveys hemihydrate to a product cyclone for accumulation (CAPEF, 1995). EM mill, or effective innovative equipment, provides drying, grinding and classifying processes of hemihydrate for further production of gypsum boards. Comparing to traditional roller mills, it contains grinding balls, which move freely between the grinding rings. A gypsum bed forms between these balls

Accelerator for gypsum slurry Kaiser Cement & Gypsum

I have discovered that a fully satisfactory and highly desirable gypsum hemihydrate accelerator can be produced by impact and ball mill grinding gypsum so that gypsum particles have fineness on the order of less than one micron in diameter without the necessity of incorporating an anti-calcination agent in the grinding mixture. I have also discovered that when ground gypsum board is used instead of land plaster, ground gypsum board does not cake and plug up the ball mill
