First, the gypsum raw material to be calcined is sent to the silo, and then sent to the calciner by the feeder for calcination. Under the action of mechanical dispersing force and hot air generated by the gas, the material undergoes processes such as dispersion, drying, calcination and strong high-speed homogenization. Calcined gypsum is ...
