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 [.]

Comminution theory focusses on the relationship between energy input and the particle size produced from a given feed size. 2 The most common breakage methods are impact and attrition, mostly by ball mills. This compares with the compression mechanism, as well as attrition, utilised in both highpressure grinding rolls (HPGRs) and vertical roller mills (VRMs).
