Design Scheme of Fault Diagnosis System for Rollers of Coal Mills

In order to solve the problem to directly measure the wear of roller of HP coal mill in thermal power plant, this paper proposes a new design scheme of wear monitoring and diagnosis system for the rollers, based on the theory of mechanical vibration fault monitoring and diagnosis, combined with CAE simulation analysis technology. The framework of a fault diagnosis system is designed and constructed, and the reasoning mechanism of wear index is discussed.
