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.

Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.

Accordingly, the wet grinding of the CNTs produced long fiber shapes. During the grinding process, the impact forces of the milling balls are different between the dry and wet conditions. The impact forces of the balls are weaker during wet grinding. Thus, it is assumed that the structure of the particles changed after dry grinding.
