Grindability Studies of Mineral Materials of Different Morphology
Light, fine grain and soft dolomite shows only 8% reduction in D 80 whereas heavy, friable and hard manganese ore shows a 29% reduction in D 80 for similar dry and wet grinding conditions. It was found that light materials are less sensitive towards mill speed (R) during wet grinding.

The lower limestone content in the raw materials leads to a reduction in CO 2emissions from calcination. As about half of limestone is CO 2, 120 kg/ton translates into roughly 60 kg/ton of reduced CO 2. The net savings in CO 2emissions might be on the order of 10% to 15%, without considering any grinding energy changes.
