Plan ahead
Systematic and planned mill maintenance is important for vertical mills, where measurements and visual observations should be conducted during stable operation. Use your stoppage inspection to conduct trial tests, measurements of the roller and a table wear profile.
Rollers, grinding table
Wear on rollers and the grinding table is your biggest maintenance challenge. It is important to regularly measure the roller and table wear profile, since worn rollers or table segments result in production loss and increased power consumption.
Roller bearings
With the sealing air and roller lubrication system the roller bearings in the grinding rollers are protected best possible. Proper replacement of filter cloth for sealing air fan and replacement of oil filter elements when needed will result in long and trouble free operation.
