Siemens is continually searching for new ways to save energy. As cement producer, have you already considered or even taken steps to reduce electrical energy consumption in your plant? Below are areas that you can review in detail. The graphs on the foldout cover the topics of typical investment costs and the expected ROI period for variable-speed drives (VSD), IE2-IE3 motors instead of IE1-motors (IE), opti- mizing auxiliary equipment (AUX), continuous vibration monitoring (VIB), total harmonic distortion check (THD), management information system (MIS), secondary fuel management (FM), mill control optimization system (MCO) and waste heat recovery and power generation (WHR). Variable-speed control If flow of process air is presently being controlled using damper, variable-speed drive can save energy, because at lower speeds, less energy is drawn from the grid. Typically, this energy-saving method is already used for larger drives. However, since small frequency inverters are more affordable today, every attempt should be made to save energy in this power range. Also, many of the belt conveyors in cement plant can run at lower speeds and still trans- port the material. Low motor speeds will also reduce the wear on the mechani-cal system. It is important to make sure that the drive motor is suitable for frequency inverter operation. Normally, an insu-lated bearing in the motor is sufficient.Siemens is continually searc
