Chat Online### 3 DYNAMIC ANALYSIS FOR BALL MILL FOUNDATION

The dynamic analysis of ball mill foundation is a typical problem of soil-structure interaction and the sub-structure method is used to estimate the structural vibration. In this study a practical case of ball mill foundation is investigated to illustrate the approach and the dynamic behaviour of structure. The concrete mat foundation and piers are modelled by FEM model and the stiffness and
