Contaminated mine enterprise ball mill hydrostatic tank

A mine enterprise 2018 - ball mill hydrostatic tank contaminated 10 - 11 a, case background mine enterprise for many years in guangzhou academy of mechanical equipment lubrication and wear condition monitoring center to carry out the equipment of oil monitoring work. Detected by monitoring purpose mainly through the oil equipment may appear early wear, so as to take timely measures to maintenance. Second, monitoring is widely research testing for the mine enterprise 1 c ball mill and ball mill 2 c two ball mill in oil monitoring, found in oil monitoring, two ball mill send the sample of the physical and chemical testing data is normal, but the 2 c black ball mill three sample appearance is obvious, there are different from those of 1 c sample of ball mill. To find out the reason, the wear particle analysis was carried out on the black sample, found three black samples there are a lot of silver grey with metallic luster, soft, grain, for the graphite particles, is the cause of black oil. Size of ball mill gear lubrication is needed to open gear oil, the oil that commonly add graphite solid additives, in order to improve the carrying capacity of the gear oil, combined with some brand the yellow appearance of the gear oil and site equipment working environment, to open gear oil pollution caused by oil containing graphite solid additives were black. And then communicate with field engineers, has been confirmed. 3, case revealed the case reflects the lubrication management shortcomings: 1) If it is running a cross contamination, disadvantages, the related system sealing measures need to be further perfected; 2) If is oil pollution arising from the maintenance that related rules and regulations, personnel training needs to improve and strengthen. （ Extensive research testing)
