ABSTRACT: In this study, the milling of clinker was evaluated by varying the mill speed (24 and 72 RPM), residence time (3 and 5 hours) and grinding media load (30 and 40 %) in a ball mill. The experiment was designed as a three level factorial statistical model. The ball mill by this stage used forged steel balls as grinding media and had its outlet in the form of grids in the end wall. The slurry from there ran straight into the tube mill inlet. The tube mill now had two chambers: first about one-third of the length, charged with …
