Grinding aids are organic compounds that are added to the mill during cement grinding. their main purpose is to reduce the energy required to grind the clinker into a given.
Jun 01, grinding aids have been used successfully for decades in cement production and many other areas, such as ceramics, pigments etc. the main effect is to reduce energy consumption and increase the grinding efficiency. additional features can be improved – e.g. powder flowability and strength development of.
Jun 01, 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.
