Pulverizing Ball Mill Failures
Each mill pulverizer is responsible for about 130 megawatts of power. When the coal quality 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.
