BHEL manufactures mills for pulverized coal fired Thermal and Industrial boilers. BHEL till date has manufactured over 1200 bowl mills and over 100 tube mills, operating in different coal fired Thermal power stations in India.

BHEL has absorbed technology from world leader M/s. Combustion Engineering USA for bowl mills. The specific range - 583 XRP/XRS to 1043 XRP covers the-state-of-the-art mills required for the Indian market and are supplied as Industrial boilers as-well-as Utility boilers of 60 MW, 110 MW, 120 MW, 210 MW, 250 MW & 500 MW capacity.

To meet the requirement of very high ash content coal with high moisture, BHEL in collaboration with M/s Stein Industrie, France of the ALSTHOM group, manufactures Ball Tube Mills for Tower-type Boiler as-well-as conventional Boiler. These are horizontal mills that grind coal by impact and attrition. They do not lose any of their grinding characteristics with time, and provide constant fineness throughout the service life of their wear parts. They are the only mills truly adapted to both, very abrasive high -ash coals and very low volatile coals which require very fine grinding.
