Gypsum Production Plant Chemical Process Plants

Gypsum production plant is a calcination unit for production of powdered gypsum (calcined). Gypsum which is coming from pit is brought to the appropriate size with gypsum jaw crusher. The hammer crusher then moves to the kiln feed size. As a result of crushing process, the gypsum size is 0-10 mm and the crushed material is pulled into the feed
