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.

2019-6-21 In the working process of vertical roller mill, it will have vibration, but these vibrations are belonging to the small scale vibration. When the vertical roller mill machine has problems, it will have serious vibration. Here will introduce the vertical roller mill vibration reasons. Feeding materials are too large. The materials will be crushed by crusher machine and then enter into the grinding mill.

2021-4-16 The center of the combination of the grinding roller and the center bracket is offset from the center of the grinding table, which causes the vibration of the vertical mill. Due to long-term wear and vibration, the gap of each connecting part becomes larger, the torsion bar cushion mat ages and hardens to lose the cushioning effect, and the thickness of the impact becomes thinner (each block is 125mm thick, and only 120mm is detected after a period of operation), making the grinding roller ...

2015-9-14 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.

2016-3-1 re vibration vertical roller mill. There are a number of reasons for high vibrations in vertical roller mills, such as: 1. Failure of the grout or cement material under the steel beams embedded in the foundation top, which allows oil to penetrate, further degrading the concrete. The anchor bolts, which are typically large in diameter, continue to ...

The vertical vibration often occurs during the rolling production, which has an influence on the accuracy of rolling mill. In order to effectively suppress the vertical vibration of the rolling equipment, the rolling mill model with vibration absorber device was established. Based on the main resonance singularity of the rolling mill system, the best combination of opening parameters was obtained.
