The sliding shaft of the mini cement plant is worn for a long time and reaches a certain thickness, the spherical body of the mini cement plant and the tile lining are difficult to combine, and scratches will occur. In general, this kind of situation is mostly because the temperature of the clinker of the hollow shaft is too high, and the temperature of the outer surface of the hollow shaft is also high, which causes the lubricating oil to be too diluted, lose its viscosity, and it is difficult to form a good oil film, causing the bushing and journal.
Friction generates heat and heats up rapidly, causing the surface of the tile lining to be melted and scratched. If there is no spare spherical tile, it can only be stopped for inspection, and the tile surface can be repaired before continuing to use. The smoothness of the scratched surface can be restored by filing, cutting, grinding, etc., but the undamaged part needs to scrape out a micro oil groove, repair the tile mouth, and empty the material and grinding medium in the mini cement plant.
Manual methods are used. , Rotate the cylinder for no-load grinding, and when it reaches a certain level, carry out a no-load test operation with the transmission part, and then load the material and grinding medium into the mini cement plant for load operation, so that the mini cement plant can resume normal operation.
