The results showed that power draw of the cement mills could accurately be predicted by the method proposed in this study. Key words: power draw, cement, dry grinding, ball mill INTRODUCTION Energy is the most important cost item in a cement plant. About 60% of the electricity consumption for cement production is used for grinding the raw material

Iranian Fuel Conservation Company (IFCO) along with the Power Ministry in Iran has set energy consumption standards for different industries. For the cement industry, the standard is set for the Ordinary Portland Cement (OPC) with the fineness of 2800 cm2/g. The standard specifies the electricity and fuel intensity for different types of cement production processes, as following:
