The Basics of Drying Gypsum
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 0.5 weight percent, then the material requires drying. A gypsum dryer is commonly used to reduce the moisture content of the ore to the necessary level.
