Coal pulverizers are extensively used in the powergenerating industry to process coal into finely ground "fines" suitable for combustion. A common type of pulverizer is the bowl mill pulverizer, in which a bowl or ringshaped grinding plate is rotated while heavy grinding wheels crush and grind coal fed onto the plate from a feedpipe.

WhatsApp: +86 18203695377FEATURES: B HEL manufactures a complete range of Bowl Mill (Pulveriser) for all supercritical non supercritical thermal power plant applications. Pulverisers are one of the major auxiliaries in a coal fired thermal power station . They are used for grinding the raw coal, so that the pulverised product at desired fineness can fed to and directly fired in the furnace of the steam generator.
WhatsApp: +86 18203695377The Process of Coal Pulverization. The coal is fed into the ball mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverize the coal to particles. Coal particles are mixed with the hot air, which enters the mill through the air inlet, and are ...
