During the operation of the ball mill cylinder, it is subjected to multiple complex loads, and the volume and weight of the cylinder is large, making it difficult to conduct modal analysis through experiments. This article takes the large ?5m×15m double sliding shoes ball mill as the research object, and uses finite element simulation software to perform modal simulation analysis on the cylinder. The first five modal parameters of the cylinder are obtained, and the operating frequency is calculated. Through analysis, the natural frequency of the cylinder is much higher than the operating frequency, and resonance phenomenon does not occur. Furthermore, through comparative simulation studies on the cylinder modal analysis of ball mills with and without double compartments, the presence or absence of double compartments has little impact on the change of the cylinder's natural frequency.
