The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. Clinker quality depends on raw material composition, which has to be closely monitored to ensure the quality of the cement. Excess free lime ...

1 Introduction. High pressure grinding roller (HPGR) crushers are used conventionally as a precrusher ead of the ball mill to reduce the specific energy consumption of the grinding stage or to increase the grinding capacity of the circuit in cement grinding circuits [3, 4, 5].
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed ...
