Claim:
1. A method of identifying potential problems of a pulverizer comprising the steps of: providing a pulverizer housing with a rotatable shaft, a grinding table mounted on the rotatable shaft, at least one journal assembly pivotally mounted on the pulverizer housing, a grinding roll coupled to the at least one journal assembly, a spring assembly mounted on the pulverizer housing; providing an angular displacement transducer (ADT) coupled to the journal assembly by a coupling and a coupling adapter, with the ADT, coupling and coupling adapter each supported by a mounting bracket for ADT measurement of angular displacement of the journal assembly and electronic signal generation corresponding to the measurement of angular displacement; acquiring ADT measurement of angular displacement of the journal assembly over time; and generating an electronic signal indicating a potential problem with the pulverizer when the measurement of angular displacement is abnormal.
