Narrow size fractions of a Portland cement clinker and a chromite sample were used as the experimental materials. The size fractions of both samples coarser than mm were used in the singleparticle impact loading tests. Ball mill grinding tests were performed with the narrow size fractions of the clinker sample finer than mm.

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 [.]
