KPBV Vertical Roller Mill Drives - Renk

of Vertical Roller Mills (VRMs) comprised gear units featuring a bevel stage and two helical gear stages. When RENK presented the first planetary gear unit for VRMs in 1979, its compact dimensions and the lower gear unit weight were a true innovation. The new concept made it possible to design an almost cylindrical gear housing – except the bevel pinion module – with a housing centerline ...

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. Grinding aids reduce the polarity of the cleaved surface and the attraction forces between particles.
