Vertical roller mill is suitable for high viscosity, the material that difficult to grind. Mainly using the stirring shaft to drive the grinding medium to do mechanical shear grinding, the material and the media full contact, grinding, complete a cycle, to achieve the fineness requirements so far. Therefore, widely used in building materials, ore, coal and other industries in the production. Favored by the user, and the user is mainly concerned about the operating efficiency and service life, these two points and its maintenance is closely related, so this article mainly describes the maintenance of vertical roller mill details.
The details of the maintenance work
1. Before you drive, should check whether the rotation of the flexible parts of the motor electrical terminals are solid and reliable, whether the reducer add enough oil or not.
2. Vertical ball mill in the use of the process, we must always check the various lubrication points, that is, lubrication and oil surface height; and the main bearing lubricating oil temperature does not exceed 55 ℃, transmission bearings and reducer temperature rise does not exceed 55 ℃, the maximum cannot exceed 60 ℃.
3. To keep the equipment in the process of smooth, no strong vibration, no abnormal noise. Feed to be uniform, to avoid abnormal equipment.
4. After the parking should be promptly cleaned to prevent the material dry skin, consolidation, affecting the next drive.
Daily maintenance details
1. Regularly check the use of fasteners, whether there is loosening and wear, whether the surface with leakage, oil leakage. If the above situation to be timely repair.
2. All lubricants of vertical roller mill should be fully discharged when the equipment is put into operation for one month, then thoroughly rinse and replace the new oil.
3. The new installation of the liner bolts prone to loose, based on the use of foot bolts after a period of time, need to be regularly checked.
4. Periodically check the wear of wearing parts, such as the liner is 70% wear or 70mm long crack should be replaced in time.
