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.
Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further arguments specific surface (low Blaine) are no technical challenge for VRMs, unpretentious Grinding Aids will show a perfect cost benefit ratio. Sophisticated cements or certain process.Blaine Fineness. 80 μmR 3 . Power Consumption of System. Coal vertical roller mill is used for grinding and drying all types of coal. 2.

Vertical roller mill application Control challenges Among the operational challenges of a vertical roller mill are the fast dynamics of the process. Compared to ball mills with dynamics changing in 15-20 minutes, vertical roller mills have dynamics changing in 2-4 minutes. The fast dynamics necessitate even closer attention to , LOI.Progress with Grinding Aids for Vertical Roller Mills. The effect of grinding aids on the comminution of cement is based on the dispersion of fine particles. It is a misunderstanding that grinding aids for vertical roller mills (VRMs) should stabilise the material bed between the rollers and the table by adhesive forces between the particles.
