Abstract

A pulverizer monitoring system is applicable to at least one pulverizer having a rotatable bowl assembly, and at least one journal assembly having a grinding roll positioned proximal the rotatable bowl assembly, wherein the grinding roll is deflected by the feedstock raw material forced under the roll during rotation of the rotatable bowl assembly. A position sensor is mounted to the journal assembly to detect an amount of deflection of the grinding roll and generates a position signal, wherein a data module is associated with each pulverizer so as to receive the position signal. A calculation engine is linked to each data module for the purpose of analyzing the position signal and other operational signals associated with the pulverizer and generating at least one characteristic pulverizer condition report. A web-based server is linked to the calculation engine to provide network access to the characteristic report(s), either real-time or historical trends. A user interface is provided with either the calculation engine and the web-based server to allow the custom setting of alarms and/or formats for the output associated with the characteristic report(s).
