Modal Analysis of Ball Mill Rotator Based on FEM Technique
In this paper, the Φ×13m centre drive ball mill is studied. After predigested the rotator with its mean characters, the FEM model of the rotator is established. After loading and solving to the rotator with FEM software ANSYS, the former ten modal natural frequencies and vibration modes are got. Through the modal analysis, the position which may be easily destroyed is found.
