Abstract
A pulverizerincludes a journal assemblywith a grinding rollerthat grinds solids in a grinding table. The oscillations of the journal assemblyare monitored by an angular displacement transducer (ADT)that creates a composite signal. A controllerreceives the composite signal from the ADT and compares it with known information of the pulverizer. It then identifies abnormal situations such as damage to a grinding roll, the grinding table, the spring assemblyand other parts of the pulverizerbefore they cause major damage.
