Rotary kilns, for gypsum calcination, are similar to cement kilns, but the main difference is that gypsum kilns are counter-flow compared to cement kilns. In gypsum kilns, the gypsum encounters a temperature of 600-650 °C when it is fed into the kiln and this temperature is decreases to around 150-160 °C at the kiln exit.
