vertical roller mill in the cement plant is smaller than the size of product from the power plant ball mill. It can be concluded that the process of grinding coal into fine particles for cement or power plant consumption uses less energy when grinding is done with a vertical roller mill rather than a ball mill.

Ball mills, that are commonly used for finish grinding, have high energy demands, consuming up to 30-42 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 pre-grinding to ball mills – is regarded as a breakthrough.
