Experimental and Analytical Diagnostic Evaluation of Coal ...

corresponded to the first and second vibration modes of the coal mill. A slip-stick motion between grinding rollers and coal bed in the bowl of the mill is believed to be the excitation source. INTRODUCTION: Coal mills grind pea-sized coal into a powder, which is blown into the furnace of a power plant. Normally, there are a number of mills that supply the ground coal to the furnace and the ...

Pulverizer Vibration Issues

The friction between the coal and grinding segments is not enough to overcome the roller bearing friction and the roll fails to turn, causing a “rumble”. This “rumble” in almost all cases is caused by very high fineness. There are two recommended courses of action to alleviate the “rumble”.
