Installed cost comparison for cement grinding systems

Abstract: 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

Cement mill Wikipedia

2021. 1. 25. However, particle size distribution is again a problem, and roll presses are now increasingly popular as a "pre-grind" process, with the cement finished in a single chamber ball mill. This gives good cement performance, and reduces energy consumption by 20-40% compared with a standard ball mill system.

Vertical roller mill for cement grinding

2014. 7. 4. The advantage of the vertical roller mill for cement (comparison with the tube mill) 1) Highly efficient grinding is possible with considerably low electrical power consumption. 2) The residence time of cement grinding in the vertical roller mill is much shorter than that of tube mill. Since system operational control response is superior, quality management on the cement product is easy. 3) Therefore the vertical roller mill for cement produces little heat for grinding
