### Cement Grinding - Cement Plant Optimization

Ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills. Closed circuit ball mill with two compartments for coarse and fine grinding are generally found in cement plants for cement ...

Diagram of cement ball mill. (Based on an image from ThyssenKrupp AG. 15) Much of the energy consumed by a ball mill generates heat. Water is injected into the second chamber of the mill to provide evaporative cooling. Air flow through the mill is one medium for cement transport but also removes water vapour and makes some contribution to cooling. Grinding is an energy intensive process and ...

10.12.2004· Furthermore, it has shown that a L/D ratio of about 3.0, which is a quite common value for cement mills, might be to high for a ball mill in a Combi-grinding plant. This was proven by the fact that there was no grinding progress observed in the last third of the total grinding path length. This finding was not effected by different ball charge filling ratios and different mill throughput mass ...
