Mar 01, 2016 The cracks nucleation was caused by lack of lubrication in the trunnion bearings, generating circumferential thermal stresses, thus the estimated temperature of the trunnion and bushing contact achieved 150 C. The lack of lubrication was originated by a logic failure which allowed the mill to start and run over the trunnion bearing bushing without the lubrication system to be turned on, that

Feb 15, 1998 As in all bearing applications, this measurement should be taken at the bearing outer ring. If the outer ring is inaccessible, take the measurement at the housing and add 15 to 20 F to estimate the correct bearing temperature. The grease provided in shielded electric motor ball bearings remains effective to approximately 200-210 F

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight

The new design has proven to improve trunnion liner reliability, durability, and maintainability of the mill trunnion linings and bearings. The main lining acts as a sleeve insert that is secured in the trunnion by a retaining ring. Dividing the trunnion liner into two pieces enables better distribution of
