Five Stages of Gypsum Production Process
Gypsum ore is dug out from quarries and mines. It is crushed and stored close to the plant. As per the requirement, the stored ore is further ground and screened to approximately a size of 2 inches or 50 mm diameter. In case the mined ore has a high moisture content (more than 0.5% of weight), it is sent to a rotary dryer for further drying.
