In the gypsum board industry, the DSJ series gypsum powder machine can break up and throw desulfurization gypsum slag cakes with a moisture content of ≤ 12% through the rotor of the gypsum powder machine, and fully exchange heat with the introduced 550 ℃ hot air to form materials with a moisture content of ≤ 1%. The materials enter the rising pipeline from the outlet duct and are carried away by the hot air into the next process. The DSJ series gypsum powder machine can also be used for drying and crushing of filter cakes in the cement industry and carbide slag in the environmental protection field. Feed particle size of DSJ series gypsum powder machine: ≤ 100mm, production capacity: 30-160t/h

Previously, desulfurization gypsum slag was often treated by landfill, which seriously polluted the environment and occupied farmland. After being treated by DSJ series gypsum powder machines, desulfurization gypsum slag can be made into gypsum powder for construction, turning waste into treasure. Moreover, the stone gypsum powder produced by DSJ series gypsum powder machines produced by Yifan Company has better performance than natural gypsum, making it a high-quality raw material for manufacturing gypsum boards.
