Wear mechanism of the rollers of MPS vertical roller mill Abstract: 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 ...
· Both a macroscopic and a microscopic analysis of the wear parts has been conducted. A laboratory scale vertical roller mill with a transparent roller/table has been developed to further understand the material movements during grinding. The development of a simple wear test apparatus has verified the type of wear mechanism dominating the process.
The MPS mill also grinds, dries, calcines, and classifies gypsum without any problem, all in a single machine, for any fineness requested and considering individual requirements. The MPS vertical roller mill - built to last, reliable and energy-efficient - is the optimum solution when it comes to performing several process steps in one unit.
