Types of Grinding Mill Structural Failures — Vytas LLC
2015-6-1 In the 1970’s and early 1980’s mills experienced “overall” structural failures. Over time, analysis and design methods have improved, and the vast majority of failures we see today are “local” failures on the mill structure. These are often caused by stress concentrations of the geometry, such as at flange endings, or other local ...
