Finite Element Analysis of Phi 2.8 m×5.75+2.25 m Coal mill

In this paper, finite element analysis has been applied on the Phi2.8 mtimes5.75+2.25 m of southern Africa that has been contracted by CBMI Construction Co Ltd. Different contact finite element model as manholes in different position of the twelve clock points are built by using ANSYS parametric design language (APDL). Stress and deformation under the actual condition were presented by calculating, and it provides academic instruction for design and adjustment of coal mill, in the end of this paper, the analytic result prove its correctness to guide the actual production.
