Coal Mill an overview ScienceDirect Topics
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%.

SAG Mill Control: It Shouldn’t be that Hard EMJ
The best way to measure load is to mount the mill on load cells. The load cells are calibrated to measure the total weight of water, grinding media (balls) and ore in the mill, but not the weight of the mill itself. While many mills today are mounted on load cells, others employ bearing oil pressure as a proxy measurement of mill load.

Mill Steam Inerting System Review and Performance
The mill system consists of coal feeders, crusher dryers, stand-alone centrifugal static classifiers and a ball tube mill. Raw coal from the feeders is mixed with hot primary air and then fed to crusher dryers. After primary crushing and initial drying with the crushers, the crushed coal is fed into the mill for pulverization.
