  • The Basics of Drying Gypsum FEECO International Inc

    The Role of Drying in Gypsum Mineral Processing After gypsum ore is extracted from mines or quarries, it is crushed and stockpiled as needed If the gypsum ore’s moisture content is greater than 05 weight percent, then the material requires drying A gypsum dryer is commonly used to reduce the moisture content of the ore to the necessary levelGypsum Processing Improvements: Gypsum ore with higher moisture content is problematic for grinding equipment By adding the drying step, a rotary dryer removes moisture and hardens the material to avoid congesting equipment in future steps High Volume Functionality: A large amount of gypsum is typically dried at one time during preDrying Gypsum for Use in Wallboard FEECO International01/04/2016· Despite gypsum's widespread use and the regular need to grind it, studies concerning the grinding of gypsum ore remain scarce In response, in this study, we have systematically investigated how certain grinding parameters (ie, mill speed, ball filling ratio, ball size distribution, powder filling ratio, grinding aid ratio, and grinding time) of conventional dry ball mills affect theAn experimental study on the ultrafine grinding of
