2021-5-21 Calcium sulfate reacts with the quick setting component of cement - C3A. During the milling process, some or all of the gypsum will dehydrate to hemihydrate. Hemihydrate reacts much faster than gypsum or anhydrite because of its higher solubility. Typically, some hemihydrate is needed for the desired setting process.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
