The effect of these layers is to cushion the grinding surface and so to greatly decrease the grinding rate. It is possible that other mechanisms are operative; for example the beneficial results obtained by the use of small quantities of carbon black as a grinding aid with cement clinker suggests some analogy with electrostatic precipitation.
Grinding aids for VRMs increase the powder flowability of the finished cement without reduction of the stability of the material bed. The impact of grinding aids depends strongly on the fineness of the cement: The higher the surface area, the bigger the attraction force and therefore the bigger the benefit from an appropriate grinding aid.
Milling aids have been predominantly developed to increase the performance or grinding capacity of cement products, and alcohol amines have been used as grinding aids in cement grinding processes for many years. Moreover, the setting point of cement produced with grinding aids is most often changed. In this study, the effects of alkanolamines and boron compounds in different mixing amounts .
