pulverizer. The major measurement parameters of coal pulverizers are typically pulverizer outlet temperature, coal mass flow, primary air flow, inlet primary air temperature, motor current and pulverizer differential pressure at various MW load. Earlier works on derivation and validation of a coal pulverizer model for control has been done [1 4].
Bowl is made to rotate at medium speed for proper pulverization of coal. Springs exert necessary pressure on rolls for grinding. Hot air through the mill besides removing coal moisture, picks up the lighter particles and takes them through the classifier and drop down the higher size particles for further grinding.
