| Abstract: | The effects of the crystal shape and crystal size of calcium sulfate dihydrate on the determination of crystal water content, the effect of stirring intensity on crystal size are presented. The reasons for the lower load of WPA production, lower filtration intensity, easy to be blocked of filter cloth and lower compressive strength of the calcined gypsum are found out. |
