Aug 25, 2011 · On average, MPC systems allow cement plants to reduce their energy consumption by 3% to 5%, as well as provide better product quality and capacity improvements. Energy management profit Armed with optimized production information, manufacturers can then project, in advance, how much energy will be required for similar loads or batches

The most important first step in controlling energy consumption is to be aware of the relative importance of the process areas where most energy is consumed. Figure 2 shows a typical breakdown of electrical energy consumption at a cement plant. The most obvious area for attention is that of grinding, both raw and cement

Ensuring efficient equipment operations and maintenance would also help guarantee optimal energy performance, as would the use of energy management systems. The cement industry can also take advantage of opportunities for industrial symbiosis – including using the waste or by-products from one process to produce another product of value – to help close the material loop, reduce energy use and …

While cement production expends energy at every step, the kiln is one of the most difficult to optimize. Modern cement plants typically use dry rotary kilns with calciners. The calciner preheats the raw material to about 900°C (1650°F). The calcination process is completed in the kiln, which heats the material to about 1200°C (2200°F)
