Today, where the ball mill is used, we have to pay attention to the care method of the sliding bearings, because once the sliding bearing is damaged, it will affect the entire operating process. Today, let's take a look at how to realize the good care of the ball mill sliding bearings.
Sliding bearings are also bearings working under sliding friction. The portion of the shaft is supported by the bearing is referred to as the journal, and the part of the journal is referred to as a shaft. In order to improve the friction properties of the shaft tile surface, the refractived material layer cast on the inner surface is referred to as a bearing liner. In addition, the sliding bearing application is generally under low speed overload conditions, or maintenance and filling the operational portion of the lubricating oil. Under normal circumstances, the Paplenoli lining in the sliding bearing does not present a flaky injury accident in a smooth condition, unless normal wear to a certain thickness, the tiles and spherical numerals cannot be well separated. Presenting a scratch.
When the ball mill is operating normally, the air shaft in the feed is suddenly fever, the temperature is very high, reached more than 200 degrees, the outer surface of the hollow axis is blue, emergency parking check, found that there is a lot of Paka Alloy in Waava, preliminary The discrimination of the tile is high temperature. Under the effects of friction and pressure, it is taken out of the wadding. The inspection found that alloy tiles appeared in many scratches, a deep scratch in the middle, but the bottom of the scratch and the thickness of the spherical body, the profile is due to the clinker of the hollow shaft. High, the surface temperature of the corresponding hollow shaft is very high, diluted the viscosity of the smooth oil, the shape is not a film, the shaft and the tiles are directly in contact with the hair, generate heat, rises sharply, abandon the surface of the tiles, and form ablation. At that time, there was no standby spherical watt, the consumer task was very heavy, and the resolution stopped repairing the damaged tiles and continued to use.
First, the scratch is stopped to stop the frustment treatment, so that it is lubricated, scrapes out of the proposed mini oil tank, and repairs the wadding. Next, the grinding body and clinker in the unloading the slag ball mill, the artificial rotating grinding body stops no-load grinding. After reaching a certain level, and the transmission local linkage no-load trial operation, after a few hours, the abrasive body and the clinker stopped the load operation, and all whether everything returned to normal.
The main feature of the ball mill is to process the oil tank and the lower milling of the lower portion of the oil tank on the sealing cover, so that the oil on the sliding journal is re-inflowing the sliding bearing box. In the outer side of the sliding bearing, an outer ring is added to prevent the outer substance from invading the bearing box. In the process system, if a fault is forced to stop, it will affect the production of the entire system, resulting in downtime economic losses. In order to improve the reliability of the zinc oxide ball mill operation, it is automatically controlled with the PC. Its control principle: In the control system, before starting the ball mill, you must start the oil pump first, and the ball mill can be started after two minutes. The two oil pumps are spare, and when a fuel pump is malfunctioned or if other reasons cannot be fuel, the oil flow signal is passed, the system is automatically alarm, and the spare oil pump is automatically activated. When the two oil pumps are in a wet ball mill manufacturer, the warranty is not reset.Oil in the fuel tank still can continue to operate for three hours.The temperature sensor is equipped with a temperature sensor in each sliding bearing. When the amount of oil supply is too small or other cause, the control system alarm is controlled by the sliding bearing temperature to 55 ° C, the ball mill is automatically stopped.In this way, it is possible to protect the sliding bearing, but also provide time for the exclusion fault.
