Design and finite element analysis of a wet cycle cement rotary kiln
The finite element method (FEM) is applied to the nonlinear analysis of a cement rotary kiln for the Raı̈s Hamidou factory (Algeria). The nonlinearity is due to contact conditions between the kiln body, tyres and foundations. The FEM is first used in a reduced model of the kiln in order to obtain the meshing criterion for the global model.
