Coal Grinding Mills System Pdf

Grinding system for most types of coal the arrangement of the grinding system enables the fine pulverized coal to be collected in a bag filter or cyclone before the clean air enters the mill fan, followed by an electrostatic precipitator. For more explosive coal, such as lignite, the filter can be installed on the pressure side of the fan.
