The answer is a litle bit complex. The specific grinding power consumption for the tube mill for cement grinding can vary a lot. A brief list of factors that influence both the mill production and the power consumption can be listed: - grinding circuit (open or close) - type of cement - clinker composition (C2S:C3S) ratio - clinker temperature

The mill had a roller presses installed for pre-grinding the raw material before it is fed to the ball mills. The feed to the mill consists of three raw materials i.e. clinker (60 %), gypsum (35 %) and Pozzolana (5 %) and is fed to the inlet of the mill using a conveyer at a rate of 50 tonnes per hour.

The order was for two vertical roller mills (VRM): one type LM 60.4 for grinding cement raw material and one LM 70.4+4 CS, the biggest Loesche VRM built for grinding cement clinker. Loesche worked with Renk to develop the Compact Planetary Electrical (COPE) drive due to the high power requirements of the LM 70.4+4 CS mill.
