where conventional wet ball milling (in closed circuit with a classifier cyclone cluster) is used to reduce the limestone particle size to 95% passing 45 µm. The Kusile ball mill specific energy is 26.5 kWh/t. The dry vertical roller mill (VRM) is a novel grinding technology that dries, grinds and classifies ore within a single unit.

In South Africa, Eskom's Kusile Power Station utilizes conventional wet ball milling to grind high-grade limestone (96% CaCO 3) to 95% passing 45 µm prior to use in the FGD scrubber. For future FGD installations under consideration, the high energy cost associated with ball milling, particularly when pursuing fine grinding, has become a ...
