Roller wear is an important cause of pilverizer failure. Roller wear is affected by many factors. In this paper, combined with the research on the abrasion of grinding roller, the wear mechanism of the soft roller caused by the soft particles of wheat was reviewed. The paper points out the influencing factors of the grinding roller wear from the characteristics of abrasive and grinding roller as well as the working conditions, and expounds the antifriction technology, which provides a reference for the study of the grinding and wear reduction technology of the grinding machine.
