Gypsum drying

Dec 21, 2017 The drying method of gypsum is divided into direct-drying type and indirect-drying type according to different heat transfers. 1. Direct air-flow drying method: The direct air-flow method is a kind of gas-solid cyclone drying technology with extremely high heat and mass transfer efficiency. For this method, Fote Machinery has researched and

    At some gypsum plants, drying, grinding, and calcining are performed in heated impact mills. In these mills hot gas contacts gypsum as it is ground. The gas dries and calcines the ore and then conveys the stucco to a product cyclone for collection. The use of heated impact mills eliminates the need for rotary dryers, calciners, and roller mills
