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 …

Where, G is another constant. The majority of the kiln feed is limestone, which does not have to be finer than 125 µm. If an argillaceous limestone (cement rock) is used, it may be possible to obtain good burnability at particle sizes considerably coarser than this (since the effective calcite grain size is smaller than the particle size).
