Raymond Pulverizer Coal Mills AMP Maintenance Forums

Aug 29, 2007 First I'd like to address Walt. A fan pulls the pulverized coal from the mill, so the mill should be negative. The air passing thru is 600F and the foaming may have begun when the mill was overheated, around 300F. I don't believe there are any oil slingers in the mill. The only bearing above static level is the upper bearing on the gear shaft
