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.

A liquid grinding aid specifically formulated to increase early and late strengths, and can be used to reduce clinker while increasing extender content, particularly in limestone extended cements. This is a high efficiency grinding aid significantly improving productivity.

SikaGrind Technology - Sika Schweiz AG

In order to keep the strength unchanged, the cements or at least the clinker com- ponent have to be ground fi ner. Such changes increase the water demand and reduce the concrete workability. Improved workability and extended slump life can be achieved with polycarboxylate polymer based SikaGrind®technology.
