coal pulverizing ball mills

Duplex inlet andoutlet ball millsare widely used in 200–300 MWcoal-firedgenerating units. Thispulverizingsystem is easily adaptable to multiplecoaltype and is simple to operate, thus it is suitable forpulverizing coalwith low grindability, high abrasiveness and required degree of fineness.

Pulverizing Ball MillFailures ... When thecoalquality is good, the unit can run at full capacity on five pulverizers. Therefore, in the event of a failure, the impact on production is minimal assuming a second pulverizer does not fail. The plant maintains two gearboxes as spares because this dual failure has occurred in the past.
