The ball milling process is carried out for approximately 100150 h to obtain uniformsized fine powder. In highenergy ball milling, vacuum or a specific gaseous atmosphere is maintained inside the chamber. Highenergy mills are classified into attrition ball mills, planetary ball mills, vibrating ball mills, and lowenergy tumbling mills.

ABSTRACT. Wet flue gas desulfurization (WFGD), using limestone with forced oxidation (LSFO), is a common Flue gas desulfurization (FGD) process where limestone reacts with SO 2 to produce gypsum (CaSO 2 O). In South Africa, Eskom's Kusile Power Station utilizes conventional wet ball milling to grind highgrade limestone (96% CaCO 3) to 95% passing 45 µm prior to use in the FGD scrubber.
