The rotation of the kiln lifts the feed up the side of the kiln, and the energy required to maintain its centre of gravity above the lowest (6 o'clock) point is the main component (8090%) of the energy consumed. In the case of kilns containing curtain chains, these also produce an eccentric load. Rotary kilns have always had variable speed drives.

 · Portland cement is produced by one of the most energyintensive industrial processes. Energy consumption in the manufacture of Portland cement is approximately 110–120 kWh ton−1. The cement rotary kiln is the crucial equipment used for cement production. Approximately 10–15% of the energy consumed in production of the cement clinker is directly dissipated into the atmosphere .
