Ball-Mills are the structures used in cement industries. This structures are mainly subjected to Mechanical static, Dynamic & Fatigue loads depending on their service subject. FEA gives better understanding of actual behavior of assembly due to various static, dynamic & fatigue loadings. Girth gear, shell, welds, crusher, foundation are critical components of Ball-Mill which are subjected to higher stresses because of various loadings. Due to asymmetric nature of static & dynamic loadings, structure may result in higher localized stresses; while fatigue loading is dangerous than other loadings as the structure will experience sudden failure without any prior indication. Hence fatigue calculations needs to be part of design of a Ball-Mill.
Process equipment manufacturer from India & Abroad approached ANALYZER to seek assistance in evaluating the design of their newly developed Ball-Mill to multiple Static & fatigue loading using simulation techniques & provide the solution in case of any observed fatigue failure. FEA also plays an important role in thickness optimizations.
