mirabilite or containing mirabilite through the solid by fresh water dissolved, get sodium sulfate solution, by chemical processing, gravity settlement or filter to remove water insoluble,, into the evaporation crystallization is carried on in a vacuum evaporation, produce the crystals and solution separation after another, with air drying method for the dry, then got anhydrous sodium sulphate products.

   The particle size of products decided by evaporation process solution.To get large particles products must be through the optimization to realize crystallization parameters, such as extended crystallization time, control the growth solution nucleation number. In the design of the evaporation crystallization optimization design, to achieve the purpose of YuanMingFen big grain products.
