Rotary kilns are similar to cement kilns but the main difference is the reverse flow of gypsum. Gypsum plaster is exposed at 600-650 C temperature during feeding in the kiln at the end of the kiln it occurs around 150-160 C. Calcination; after crushing process gypsum size is reduced to 0-8 mm. Sized gypsum feeds the kiln regularly by .
