Abstract

A pulverizer 60 includes a spring assembly 10 that urges a grinding roller 72 of a journal assembly 68 onto a grinding surface 66 of a grinding table 64. The force applied is monitored by a load cell 32 located within spring assembly 10 that creates an electronic signal. A controller 83 receives the electronic signal and stores and/or displays it and alternatively acts to adjust the applied force to a desired value. Alternatively, adjustable forces or mechanical dampening may be applied to journal assembly 68 by controller 83. Alternatively, additional sensors may measure displacement of the journal assembly and rotation of the grinding table for other calculations.
