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
OPTIMIZATION OF CEMENT GRINDING OPERATION IN BALL MILLS Several energy efficient options for cement grinding are available today such as vertical roller mills, roller presses (typically in combination with a ball mill), and clinker pregrinder- s with ball mills. Ball mills have been the traditional method of comminution in the mineral processing
As the Vertical Roller Mill (VRM) becomes more widely accepted for new cement grinding systems differences in installed costs between a VRM and a ball mill system are more frequently discussed. Past comparisons of total installation costs for a ball mill with high efficiency separator versus a VRM have indicated the higher equipment costs associated with the roller …
