The increasing use of vertical roller mills (VRMs) in the production of cement to reduce power consumption and CO 2 emissions has resulted in an increasing need for VRM optimisation. As cement producers look to protect profits as well as their environmental reputation, a process audit can identify the root causes of issues to help plan for …

A case study regarding the integrated energy optimization for the cement industry is presented in . The optimization goal is finding the minimum operational cost with constraints like maintenance and meeting the production targets. In one application, different tariffs are assumed for peak, standard and off-peak periods.
