Progress with grinding aids for VRMs
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

Addressing the Unwanted Impacts of Grinding Aids
Grinding aids reduce the attraction force of finely-ground cement particles and avoid agglomeration. Consequently, separator and mill efficiency increases, which reduces energy consumption. Moreover, the fluidity of the cement powder rises, which facilitates its transportation on air-slide conveyors, as well as with the unloading of silos, particularly dome silos, and silo vehicles.
