CHAENG has many years of milling equipment maintenance and manufacturing experience, the face of the vertical roller mill wear also has its own experience and solutions!

Maintenance service for slag vertical mill as below:

Slag mill wear characteristics both squeeze wear and jet wear. Squeeze wear mainly occurs on the grinding parts and slip occurs, and jet wear occurs mainly inside the mill parts subjected to air-jet dust carried.

Slag mill stand body wear-resistant wear liner, separator rotor blades, static blades are made of composite wear-resistant steel, the main roll of protective sleeve also wear-resistant steel, the roller shaft and the mill shell by the soft Rubber seal, normal work, the main roller up and down displacement, soft rubber sealing performance is poor, under the action of a strong negative pressure in the mill, the mill formed in this air leakage, strong air flow will be wear-resistant steel plate here, wear this point of wear and tear The most serious, In addition, the mill circulating air flow caused by strong erosion of other parts, it can not be ignored.

During overhaul, we found that the main roller shaft and the lower part of the soft connection seal were ground with a pit of about 10 mm in shape like a hat, which may wear out of the shell if not repaired in time. We use the opportunity to repair the separator, grinding lining inspection, maintenance, in order to ensure the reliability of slag mill vertical operation, reduce the wear and tear on the vertical grinding mill harm.

Operation, according to the actual situation to adjust the frequency of the main fan speed, mill pressure drop, into the mill negative pressure, the negative pressure mill can reflect the size of the wind and wind speed. Large pressure drop, negative pressure, said a large wind speed, large air volume; the other hand, the corresponding small wind speed wind speed. The stability of these parameters indicates the stability of the air volume, thus ensuring the stability of the material bed.
