In contrast to tests with ball mills, the effect of grinding aids in a VRM is already visible and audible after 10-20min. Before the addition of the grinding aid, a blank test was run to confirm reproducibility (See Figure 2). Image: The Loesche pilot mill used by Sika. Image: Figure 2: Blank tests show excellent reproducibility. Starting from this baseline, the new grinding aids were

In a VRM the grinding takes place by pressure and shear force. The clinker passes within seconds between roller and table. The energy input to the material during one passage between grinding rollers and grinding track is relatively low. The thick-ness of the material bed between roller and table is a multiple of the particle size.

TAVERO VM grinding aids mitigate these issues by requiring less water for stable VRM operation. For example, a cement plant in Europe was running a VRM and spraying water at 1.5% and milling at 100 C. Using a custom-developed TAVERO VM cement additive, they achieved 28-day strength gains at +3 MPa through chemical activation and +3 MPa by
