Cement mill separator, or cement separator, is a type of equipment that was widely used in the cement grinding system and raw mill system of cement plants.The function of the separator is to separate the fine-sized particles from the coarse-sized particles, so as to avoid material condensation and over grinding in the mill, and improve the milling systems grinding efficiency.
Cement plants form a challenging environment for rotating equipment. Significant amounts of silica dust occur as a by-product of certain construction processes. Over time this dust subjects rotating equipment, including Raw Mill fans, to high levels of erosion which ultimately reduces the plants output over time.
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.
