Changing the rubber lining of a rod mill to a steel lining – what impacts does this have on the operating parameters of the coal grinding mill?
It doesn’t have a significant impact; it just results in more noise, and less grinding rod needs to be used.
What is the general wear condition of steel linings?
The service life of the steel lining plate should be 7 to 8 years without any problems, but this is only possible if it is properly maintained; any leakage of grout from the cylinder must be addressed by tightening the bolts promptly. Otherwise, the loose ends of the bolts can enlarge the holes in the lining plate, leading to its detachment and subsequent failure.
