These calcination methods (equipment) use a built-in heating tube to receive heat between the desulfurized gypsum, and the heat source generally uses steam, heat transfer oil or hot flue gas. Because it is indirect heating, the heat transfer rate between the material and the heat source is slow. After the gypsum is slowly heated and heated, the water is slowly dehydrated to form a hemihydrate gypsum. The advantage of low-temperature slow calcination is that the product quality is uniform and stable. Due to low-temperature calcination, most of the calcined products are hemihydrate gypsum HH (about 88%), a very small amount of anhydrite AIII (about 2%) and dihydrate. Gypsum DH (less than 1%), crystal water content is 5.5% to 6.0%, so the building gypsum powder produced by low-temperature slow calcination is stable in quality, stable in phase composition, slow in coagulation, and low in standard consistency.
