operation costs, vertical mills have made their way into the cement industry. At first these new systems were employed for the grinding of solid combustibles and kiln-feeding raw meal. In the past decade, however, the new generation of vertical mills has demonstrated to be a competitive solution for final cement grinding as well.
The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time
