Ball Mills Coal Power Plants

The coal brought should be maintained around 10 moisture content immediately before it is used the coal needs to be ground as powder before it is burnt there are five mills which are used to pulverize grind the coal basically four ball mills work at a time while another one is in standby

Furthermore in the ball race mill the motor current varies with load saving power when the mill is running at part load excellent wear characteristics the mill design facilitates that a major portion of the grinding occurs coal to coal rather than coal to metal increasing the wear life of the grinding elements

Coal power plant ball mill li ne ball mill coal power plant from g power plants power plant water use for ix comment on us is evident that apart from heat discharged with combustion gases from a coalburning plant and any difference in thermal efficiency which affects the amount of heat to be dumped in the cooling system there is no real difference in
