The material of the liner and the heat treatment process directly determine the mechanical properties of the liner, and will have an important impact on the wear of the liner. If the material of the liner is improperly selected and the heat treatment process is unreasonable, the fatigue strength and service life of the liner will be greatly reduced, and the requirements of the vertical roller mill grinding…Continue
Pay attention to the heating and cooling operation of the vertical roller mill. Most manufacturers do not pay attention to the heating and cooling operations of vertical roller mills, and fail to realize that reasonable heating and cooling operations can prolong the service life of key large bearings and wear parts.
When welding construction in the vertical roller mill, attention must be paid to the…Continue
Ensure the normal operation of the sealed fan. The wind pressure should not be lower than the specified value. Under normal circumstances, it should be kept above 20Bar. Regularly check whether the sealed air duct is damaged; the joint bearing at the joint between the sealed air duct and the vertical roller mill in the grinding cavity Whether the flange is disengaged, etc.
At the same time, in order…Continue
The sealing air system is a key link to ensure that the oil seal of the grinding roller is not damaged. The sealed air system consists of a sealed fan and an air duct. The blown wind starts from the sealed fan and finally reaches the sealed air duct. The grinding roller installed on the grinding disc of ultrafine vertical mill seals the air to form a space.
In this way, an annular seal cleaning…Continue
