Operating data from a coal mill is used to compare the fault detection observer-based method and PCA/PLS models based approach. There are 13 process measurements available representing different temperature, mass flows, pressures, speed etc in the coal mill. The measurement is not updated, if the variation is less than 1%.
Mill operation. The mill in operation carries out four functions simultaneously namely, grinding, drying, classification and transportation of product to the burners. The coal mill is not the only component involved in the combustion path which must be controlled.

Most commonly used mills for coal grinding in cement plants are closed circuit air swept (Single chamber) ball mills and vertical mills. Ball Mill: Single chamber ball mills (with classifying liners and dam ring) with drying chamber and static or dynamic separator are commonly existing for coal grinding in cement plant for one or more kilns as per capacity.
The coal mill utilises compression and shear force generated between the large rollers and the rotating table to crush and grind raw coal, removing the need for a separate piece of equipment for crushing.
01-04-2014· The mill model is running in parallel with the power plant coal mill operation; the measured and predicted outputs are displayed on the computer screens in the power plant control room. When the measured and predicted mill outputs are over the pre-set threshold values, the system will raise alarm reports to give warning signals.
