VRM grinding parameters. One of the VRM’s great advantages is its versatility. The mill can easily grind multiple types of cement under different operating parameters and with little to no transition time. To achieve the full benefits of the VRM without problems, we should understand the effect of the different operational modes on the cement.Grinding 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.
