    Cement milling and gypsum dehydration. Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO 4 .H 2 O. On further heating, hemihydrate dehydrates further to a form of calcium sulfate known as soluble anhydrite (~CaSO 4 )

    important operation tips for cement vertical mill

    The influence of material moisture on the vibration of the mill can not be ignored. If the moisture content of the material is too low, it is difficult for the dried material to reliably form a stable bed on the grinding disc, which inevitably causes the mill to vibrate. When the moisture is too high and the layer on the grinding disc is too low, it is easy to form a cake, which increases the vibration of the mill
