Aug 04, 2021Gypsum is usually added to the cement during the grinding of clinker in a ball mill. The heat generated in the ball mill during this process is said to affect the gypsum hydration state. The dehydration rate of gypsum depends on the intensity of heat [9,10,11,12,13]. Usually, natural gypsum (CaSO 4.2H 2 O) is added during the ball mill during
