• Vertical Roller Mill (VRM) cement produced with low mill outlet temperature should not be stored in a silo together with high temperature cement (>70 degree Celsius). High mill outlet temperature • Cement produced at high outlet temperatures (>110 degrees Celsius) had significantly dehydrated gypsum.

The cooling of cement is an important step prior to storage in mitigating gypsum dehydration and subsequent moisture liberation which can lead to lump formation. Recommendations vary but it is generally accepted that with mill outlet temperatures of around 110ºC – 120ºC, cooling to below 80ºC is necessary to avoid this reaction.
