Raw Mill Optimization Module The Raw Mill Optimization option controls both the temperature, the feed rate to the mill and the separator speed in order to achieve the required throughput for kiln. Where starting the mill requires dampers to be moved, to change gas flow paths, the module will also respond to these effects to keep the system stable.
Recently, the vertical roller mill having great grinding performance is widely applied to the raw material grinding process. However, tube mill, which has about 30% poor grinding performance as power consumption, has been still used many existing cement plant. The improvement of this tube mill grinding system is highly expected. Descriptions
