Wear mechanism of the rollers of MPS vertical roller mill

摘要

This article, based on the abrasion condition of the rollers on the working field, analyzes the movement characteristics of the material layer of the vertical roller mills from several aspects, such as the tangent speed difference between the roller and the grinding table, the “piles up” phenomenon as well as the flow forms of the material layer. Then we further studied the influence of the movement of material layer on the roller wear and the influence of roller wear on the mill vibration.
