Vertical roller mills grinding an OPC of low fineness, say around 3000 cm2/g (Blaine) can operate without grinding aid, but even when grinding to that low fineness, grinding aid improves the output rate as well as the specific energy consumption. Recent experience has shown that water has an effect similar to that of a grinding aid.
