Ball mills, that are commonly used for finish grinding, have high energy demands, consuming up to 3042 kWh/t clinker depending on the fineness of the cement. Complete replacement of ball mills by vertical roller mills (VRMs) with an integral separator – as opposed to the use of VRMs as pregrinding to ball mills – is regarded as a breakthrough.
