Application note AC drives improve cement kiln control .

Application note AC drives improve cement kiln control and reduce energy consumption Application description The kiln is the most critical element in the cement making process. It is where the chemical processes occur that turn raw mix into clinker. The kiln also consumes the greatest amount of energy (fuel plus electricity) within a cement plant.

Unprecedented kiln performance using advanced process control

Controlling a cement kiln has always been a challenging task for cement plant operators. A kiln is very sensitive to many different, inter-related factors and a poorly run kiln can dramatically increase operating costs. It is common when introducing some more automation to the control room that it is met with some resistance at first.
