failure mode of ball mill. SUAMG Machinery is professional mineral processing equipment manufacturer in the world, not our equipment has the excellent quality, but also our product service is very thorough.

However, there is a marked increase in stress towards the end face of the shell for the longest trunnion with a moment arm of 1115 mm. What is particularly dangerous in this case is that the greatest stress lies at the points of attachment and that it has different directions in the upper and lower parts with an attendant risk of fatigue.

Cutter bodies will wear and fatigue over time; inspect tool before each use. Recommendations. Maximum Depth of Cut (DOC) for finishing should be less than or equal to 10% of ball diameter. Stepover should be greater than or equal to DOC. For roughing operations, maximum recommended Width of Cut (WOC) and DOC are 30% of ball diameter.

fatigue damage. This situation is inherent in the trunnionmounted ballmill. Membrane stresses are illustrated in Fig. 2. These stresses are high when compared with the rotating bending stresses inFig. 1,butthey areunidirectional in nature andarenotsodamaging asafullyreversed stress. In Figure 2a,the overall bending stresses are com
