2013 3 1 Coal mills are used in coal fired power plants to grind crushed coal lumps with several cm diameters to very fine powder in the order of 50– diameter. A further task of coal mills is to dry the coal particles avoiding wet coal conditions during combustion. This is achieved by hot air passing through the mill which evaporates the coal moisture.

Monitoring and diagnosis of coal mill systems are critical to the security operation of power plants. The traditional data driven fault diagnosis methods often result in low fault recognition rate or even misjudgment due to the imbalance between fault data samples and normal data samples. In order to obtain massive fault sample data effectively based on the analysis of primary air system

A wide range of flow rates from 750 to 5300 kg/h of coal at 60 65 solids concentration has been covered with both single and multiple passes through the mill. Particle size distributions and power consumption have been measured.
