In coal-fired power generation, it is necessary to pulverize coal, and a vertical roller mill with excellent crushing efficiency has become the mainstream. However, In the process of pulverization by compression and shear, abnormal vibrations, which are considered to be self-excited vibration, occurs rarely. As a method of reducing 网页2019年9月28日 The vibration analysis process will be employed in the network using a series of complex nodes and trained according to the reference spectrum analysis.
