grinding system. For most types of coal, the grinding system is arranged so that finish ground coal meal is collected in a bag filter or a cyclone followed by an electrostatic precipitator, before the cleaned air enters the mill fan. For more explosive types of coal such as lignite, the filter may be installed on the pressure side of the fan.
