Clinker grinding technology is the most energy-intensive 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 …

The main processes involved in a cement grinding unit are: Clinker grinding: This is the main process in a cement grinding unit, where the clinker is ground into a fine powder using a ball mill or combi mills (RP+ Ball Mill) or vertical roller mill circuit. The grinding process is controlled to achieve the desired fineness of the cement.
