Vibration Analysis of a Vertical Roller Mill: Modeling and ...
Oct 23, 2014 · In this paper, vibration characteristics of a Vertical Roller Mill (VRM) are studied by using physical parameters of an operating VRM. The mathematical model is derived and simulated for a set of working parameters. Mechanical properties of the grinding material and the physical properties of the mechanical construction are used in the vibration model in order to obtain more realistic results.
Vertical Roller Mills Vibration Analysis
The vibration of mill body of vertical roller mill is a normal phenomenon exists in working condition, reasonable vibration is allowed, if the mill has a violent vibration, it will cause damage to millstone, roller lining and accessory equipment.
The vibration control of raw material vertical roller mill ...
The vibration of mill body of vertical roller mill is a normal phenomenon exists in working condition, reasonable vibration is allowed, if the mill has a violent vibration, it will cause damage to millstone, roller lining and accessory equipment. Therefore, vibration values in working condition should be controlled strictly within a scope of allowance (below 20mm/s is better), the mill can operate stably.

The causes of the vertical grinding vibration and the treatment measures are as follows: 1) The foreign matter inside the mill causes vibration. Metal foreign objects from inside and outside the mill, such as wind guide vanes, and tools left over after repair. If it is a small metal, it can lift the grinding roller and reduce the air suction, and take it out from the material returning port; if it is a large metal, it should be …

mill indicates more internal circulations and more fines. As a re-sult of the higher ∆P mill, the mill vibration increases (8-10mm/s), which results in a good opportunity to test the effect of the grinding aid. In contrast to tests with ball mills, the effect of grinding aids in a VRM is already visible and audible after 10-20min.
