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 …
Simply put, the roller press is the most energy-efficient grinding machine on the market. Since its commercial introduction into the cement industry by KHD in the 1980s, hundreds of them have been installed in the cement and minerals industries, in both finish and semi-finish applications. And with the lowest specific energy consumption among comparable …
During heat up there should be a sufficient air flow through the mill to force the heat transfer to the grinding part – forced convection. A sufficient air flow will result in a mill differential pressure of> 5mbar. The duration of heating should be at least until the temperatures after mill and after bag filter reach 85° C.
In fact, in the same application a Vertimill® has 50% less footprint than a ball mill. Lower operating cost Vertimill® is an energy efficient grinding machine. They tend to grind more efficiently than for example ball mills with feeds as coarse as 6 mm to products finer than 20 microns. This provides up to a 40% higher energy efficiency.
