Choosing ball mill lubrication bearing maintenance skills

　　In the increasing use of the mine mill, pay attention to the use of the sliding bearing, because once the sliding bearing is damaged, it will affect the entire process. Take a look at how to achieve a good maintenance of the ball mill slide bearing. Sliding bearings are also bearings working under sliding friction. The shaft portion supported by the bearing is referred to as the journal, and the portion that matches the journal is referred to as a bearing. The friction reduction of the material layer on its inner surface to improve the frictional properties of the bearing pad surface is referred to as a bearing liner. In addition, the sliding bearing application is usually used under low speed overload conditions or is used in a region where it is difficult to maintain and lubricated. Under normal circumstances, the Pap Alloy line in the sliding bearing does not have a burn scratch accident in the case of smooth smoothness, unless normal wear to a certain thickness, the tile lining and the sphere cannot be separated, and the scratches exist. When the ball mill is operating normally, the hollow shaft of the feed is suddenly warmed, the temperature is high, reaching 200 degrees. The color of the hollow axis becomes blue. Emergency stop checking that there are many Bayene alloys in the spherical tile opening. Absorbed by high temperature. Under friction and pressure, it is removed from the mouth. The inspection found that there were many scratches in alloy tiles, and the middle scratches were deep, but the bottom of the scratches and the spheres also had a thickness of two-thirds. The reason for the analysis is the temperature of the clinker into the hollow shaft. High, the surface temperature of the corresponding hollow shaft is high, the viscosity of the dilution of the light oil is formed, and the shaft is directly in contact with the tile liner, generating heat, has increased dramatically, and the surface of the lining is ablated to form a scratch. At that time, I thought that there was no spherical tile, and the task was very heavy. The resolution stops repairing damaged tiles and continues using it. First, the scratches should be stopped, and the grinding and polishing should be processed, and lubricate. On the undeaded appearance, the conventional micro oil tank is scraped off to repair the oral cavity. Next, the grinding body and clinker in the slag ball mill is removed, and the grinding body is manually rotated to stop the airborne grinding of the tile liner. After reaching a certain level, the engine portion is connected to the drive for an air-load test operation. After a few hours, the grinding body and clinker were loaded to stop loading and check if everything returned to normal.

　　The main feature of the ball mill is to processed the oil tank on the sealing cover, and milling the lower portion of the oil tank is performed to form a gap in the sliding journal to return to the sliding bearing housing. In the outer side of the sliding bearing seal, an external retaining ring is increased to prevent foreign matter from invading the bearing housing. OKIn the system, if the device fails and is forced to stop, it will affect the production of the entire system, resulting in economic downtime loss. In order to improve the operational reliability of the zinc oxide ball mill, the PC is automatically controlled. Control Principle: In the control system, first start the oil pump before starting the ball mill, and start the ball mill after two minutes.
