During the operation of the vertical roller mill product, the contact surface is subjected to multiple grinding and grinding, which will cause the overall product quality of the vertical roller mill to be damaged. The timely maintenance and protection of the vertical roller mill plays a key role in prolonging the life of the vertical roller mill.

The main vulnerable part of the vertical mill is the surface where the grinding disc and the grinding roller meet. It is necessary to add a thick layer of wear-resistant layer to the contact surface of the grinding roller and the grinding plate, and this layer of wear-resistant layer needs to be based on its quality. Determine the frequency and cycle of replacement. Xinxiang Great Wall will carry out multi-layer surfacing welding when producing vertical mill grinding discs and grinding rollers to ensure the service life of the wear-resistant layer and reduce the frequency and cycle of replacement.

Operation plan and construction of vertical mill:

Make a detailed plan for the operation of vertical mill equipment, including production volume, work and rest time, professional maintenance department, etc. Reasonable work arrangement and preventive measures can prolong the service life of equipment and accessories and improve production efficiency. Specifically, do the following:

1. Make a reasonable production plan to avoid overworked equipment.

2. The central control department will conduct real-time monitoring of data parameters, and find out abnormal problems such as finished product quality and production efficiency and eliminate them in time.

3. Lubricate or replace the slightly or severely worn parts of the vertical mill.

Vertical mill breakdown maintenance:

When the vertical mill has specific failure phenomena, such as the powder collector does not produce powder, the bearing is locked, and the dust at the feed inlet is abnormal, such common failures are described in the detailed technical description of the vertical mill equipment. It cannot be handled arbitrarily. It is necessary to find a technician or check and eliminate it under the knowledge of the technician. The whole process of troubleshooting should be carried out under the condition of power failure to avoid other accidents.
