The grinding of the finished cement consumes approximately one third of the total electrical energy of a cement plant. 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
Get Priceanism of grinding between VRMs and ball mills, in terms of how grinding occurs, the residence time, the level of repeat grinding and recirculation factors, among others. In a VRM, comminution occurs by pressure and shear forces that are introduced via the grinding rollers. In ball mills, com-minution is mainly done by impact, with the grinding
Get PriceGrinding aids reduce the adhesion forces between particles without a negative impact on the stability of the material bed and fluidisation. In ball mills, where the grinding time is longer than in a VRM, excessive powder flowability can lead to insufficient or inefficient grinding because the material flows too fast through the mill
