Gypsum rotary kiln is a kind of calcining equipment with excellent performance and excellent quality. It has many advantages, which are reflected in many aspects. A vertical preheater was installed at the end of the gypsum rotary kiln so that the waste heat of flue gas at the end of the kiln was directly transmitted to limestone.

The heat for drying is typically is supplied by waste gases from the rotary kiln or clinker cooler. For grinding, large cement plants use high speed roller mills or bowl type grinding mills, and smaller plants use tube mills packed with paper bags filled with iron grinding balls.
