Critical-equipment component maintenance key to coal-handling .Aug 1, 2008 . Conducting CBM for coal-handling plant (CHP) equipment requires: - Establishing an alarm level based on variations of a physical parameter, such as vibration, power consumption, temperatures, etc. - Predicting impeding failures of critical plant components, such as crusher rotors, conveyor pulley shafts,.coal crusher failure,Critical Equipment Maintenance - Plant Maintenance Resource CenterThe output size of coal affects the performance of CHP. Naturally these two hard surfaces are critical parts. One of these surfaces are known as grinding plates and other may known as rings, hammers etc. The linkage between crusher rotor and drive assembly are also critical parts. As failure of these linkages will stop.
