Ggypsum Dehydration Issue In Ball Mill

hydration of anhydrite of gypsum (caso4.ii) in a ball mill,the hydration of an anhydrite of gypsum (caso 4.ii) in a ball mill was studied as a function of time and temperature. the amount of gypsum formed at different intervals of time was determined by weight loss method and powder x-ray diffraction technique. specific surface area at different time intervals was determined by laser granulometric method..material and energy balance of production of …,in the gypsum factory komar, d. vakuf the gypsum production process is carried out by dehydration in fluidization layer. the procedure consists of thermal treatment of raw gypsum in the ball mill in which at the same time the process of drying, milling and dehydration dihydrate in to semihydrate is taken place. mill capacity is 10 t/h..operational experience from the united states' first,heated up as much as in a ball mill. this means that a lower degree of gypsum dehydration could occur. a lesser degree of gypsum dehydration is not problematic considering two conditions; the inability to adequately control temperatures in ball mills creates an environment where operation is at the extreme of the gypsum experimental study on the ultra-fine grinding of gypsum,abstract. gypsum is a crystalline form of hydrated calcium sulfate (caso 4 ·2h 2 0) generally used in cements and plasters in the construction industry, though also in paints, fertilizers, medicines, papers, and textiles. for use in these materials, gypsum must be ground finely (< 100 μm), if not ultra-finely (< 10 μm), for which ball mills are.
