Jun 01, 2012· Highlights We analyzed a raw mill and investigated the first law and second law efficiency values. Performance assessment of a raw mill indicates that the grinding process involves energy and exergy losses. The ambient air conditions affect efficiency and production capacity of the mill. The specific energy consumption for farine production is determined.
A closed circuit has a high production rate, low specific power consumption and produces high quality cement as compared to an open circuit. Thus it can be used in place of an open circuit. Design modification can be defined as structural changes made on a pre-existing system. For grinding circuits, an open grinding circuit can be modified to a ...
