Saving Energy with Grinding Aids

Sika grinding aids for energy-efficient cement production save approx. 64 megajoules per ton cement (0.035% dosage) compared to grinding performed without these aids. Only around 10 megajoules of energy are consumed in the manufacturing chain for the grinding aids. This results in net savings of 54 megajoules per ton cement, roughly equivalent to the daily electricity consumption of a Swiss household.

Massive Potential

Extrapolated to the global cement demand of 3 294 million tons in 2010, Sika grinding aids could theoretically have achieved energy savings equal to the annual power consumption of around 6.5 million households.
