Problems of idling and full operation of the mill
Thread Content
How to determine whether a mill is running under no-load conditions or at full load? How to deal with it?
With physical methods and experienced operators, it’s possible to make an approximate judgment based on sound, but it seems difficult to determine exactly to what extent the wear has progressed. I’ve heard it; the sounds are very different. Also, the coal feeding amount can be determined then. This post was last edited by GSP on 2009-2-16 13:02.]
On-site operators should be aware of the specific situation!
Mainly listen to the sound of the grinder; when it is running idle, there are loud metal collision sounds between the rods as well as between the rods and the grinder’s lining plates. The sound is muffled when fully worn. Treatment: During idle grinding, add water and coal. At full grinding, reduce coal and water appropriately. Additionally: When making judgments, factors such as the mill’s power and the valve position of the small coal slurry outlet can also be considered.
Current of the coal grinder and tank level
Judging from the sound of the grinder, an empty grinder makes a clear sound, while a fully loaded grinder produces a muffled sound
The current in the grinder keeps fluctuating, so how can one determine that? It should be possible to tell by listening to the sound.

An introduction to internal operations, an introduction to external operations – so what happens if the load status shows something?
