Vertical mill belongs to large industrial equipment, its parts is as much as self-evident. But because of the mill working environment is relatively poor, parts of the wear layer is also quite big, this time on the need to make a timely maintenance of fittings.

Vertical mill grinding roller, grinding, lining board are important wear parts of vertical mills, need good abrasion resistance. But if it is not in the operating process master the correct method of operation, is easy to cause damage to the wear parts, thereby reducing the equipment operation efficiency, increase the equipment maintenance costs.

In order to extend the vertical mill grinding roller, grinding, lining service life, we can start from the following aspects:

1, to select a suitable material

Different wear material opposite grinding roll, grinding disc and liner of each are not identical, material impurities, high hardness, a great influence on the wear resistance, such as the increase of quartz and pyrite content, the wear parts wear increases, so choose the appropriate materials is necessary.

2, to ensure uniform feeding

According to the material selected hard suitable degree of particle size, typically, harder material diameter in 3 cm below the ideal.

3, strictly metal block into the vertical mill

When necessary, in the raw material into the grinding before the installation of the iron remover, lest the metal material falls into the vertical mill to damage the related spare parts.

4, the timely replacement of wearing parts

Maintenance, can open the movable casing, replacement of wearing parts shall be timely; dynamic disk spindle before driving, check the machine there is no abnormal sound, found that the problem should be timely treatment, can't let to stop the operation of equipment.

5, maintenance checks roller sleeve of the rolling bearing

Especially when the need to change the grinding roll, roll sleeve in the rolling bearing cleaning, and timely replacement of damaged parts.

To sum up, to do the opposite of mill accessories maintenance is not difficult, as long as careful can do. Do the opposite mill accessories maintenance can ensure the normal operation of the equipment and the service life of equipment, to serve us better.
