Once normal coal flow is applied to the mill, a full mill test should be conducted. This should include isokinetic coal sampling and dirty airflow measurements through each fuel line to determine air fuel balance and coal fineness. Primary airflow "Hot-K" calibrations of the primary airflow measuring element should also be conducted.

Further, the mill performance and availability is also influenced by some common mill faults like mill choking, coal hang up in mills, fire or explosion, and wear in the milling components such as rollers, grinding table, and vanes of the classifier.
