The coal mill is one of the important auxiliary engines in the coal-fired power station. Its operation status is directly related to the safe and steady operation of the units. In this paper, a model-based deep learning algorithm for fault diagnosis is proposed to effectively detect the operation state of coal mills. Based on the system mechanism model of coal mills, massive fault data are

Evidence reasoning (ER) combined with dimensionless index method can be used in rotating machinery fault diagnosis. In ER algorithm, reliability is mainly obtained in two ways: distance-based method and correlation measure by set theory. In practice, the distance-based method cannot generate high-discrimination reliability in high-coincidence data like dimensionless index data. Therefore

It can be seen from Figure 8 that for the 200 test samples under working condition 1, only three sets of ball fault samples are misdiagnosed as inner ring fault, and the accuracy of fault diagnosis is as high as 98.5%. The accuracy of fault diagnosis under the other three working conditions also reached 94%, 96%, and 95.5%, respectively.

Gear fault in a ball mill. This ap-plication deals with a ball mill ma-chine driven by two AC motors—each through a two-stage reduction gearbox. The motors are 2MW power, 5kV volt-age and 1,000 rpm speed; the gears are chevron-type. During one experiment it was known from the operator that the high-speed pinion of one gearbox had one cracked

From these results, analysis including the ball faults within the fault diagnosis requires more sophisticated techniques. These include data sets 118 to 121, 185 to 188, 222, 224, and 225. These data sets are used within this paper; therefore, there is potential value of the computational expense of the methodology proposed within this paper.
