Clinker grinding technology is the most energyintensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits significantly, the [.]

The effects of balls and cylinders on the clinker's specific rate of breakage were investigated. The results showed that the specific rate of breakage provided by cylinders is higher than that of balls. − + mm is an optimum feed size for 20 mm diameter balls and 20 × 20 mm diameter that feed size, the value of Si is maximized.
