BHEL PRESENCE IN COAL MILLING EQUIPMENT Pulverisers are one of the major auxiliaries in a coal fired thermal power station. They are used for grinding the precrushed raw coal, so that the pulverised product at desired PF fineness can be fed directly to the furnace of the steam generator. BHEL MANUFACTURE BOWL MILLS AND BALL TUBE MILLS Bowl
PRINCIPLE OF OPERATION Raw coal coming from feeder gets ground between the grinding rolls and bull ring segments installed on the revolving Bowl. Bowl is made to rotate at medium speed for proper pulverization of coal. Springs exert necessary pressure on rolls for grinding.
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].
The BTM is a lowspeed mill that primarily grinds coal by impact and attrition. The VRM is a medium speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed
