    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. The Raw Mill Optimization Module stabilizes mill

    Jan 01, 2018 In this section, energy and exergy analyses of a raw mill system in the cement plant were performed. To achieve this, the mass and energy and exergy balance equations for the input and output flows of the raw mill process were evaluated. The mass balance equation of the raw mill process can be written as: (11) m ˙ 1 + m ˙ 4 = m ˙ 2 + m ˙ 3
