In 1984, UBE developed the 2Way System where deaeration and compaction of material bed on the grinding table is achieved by subroller pressing thereby improving the material coefficient of friction (μ). The essential countermeasure to suppress mill vibration is to increase (improve) friction coefficient of material in the grinding area ...

An innovative approach to conditionbased maintenance of coal grinding subsystems at thermoelectric power plants is proposed in the paper. Coal mill grinding tables become worn over time and need to be replaced through timebased maintenance, after a certain number of service hours. At times such replacement is necessary earlier or later than prescribed, depending on the quality of the coal ...
