In order to study the hot Compact Strip Production (CSP), four-high mill vibration characteristics, and vibration suppression method, the roller system structure stability was analyzed and calculated at first in the paper. And then, the mill stand gap was measured at field and its influence on roll transverse vibration was analyzed. The drum gear coupling effect on the roller system stability ...
Mar 01, 2016· 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.
A lumped mass model with six degrees of freedom for the vertical vibration of four roller hot strip rolling mill stand was proposed, while its natural frequencies were calculated by MATLAB software. The numerical calculation results were proved more accurate through field vibration test. This vertical vibration model can be applied for dynamic simulation and structural dynamic modification ...
• Low-vibration mill running, even in partial load ranges down to 20% of the mill load, thanks to individually-guided grinding rollers. • The specially-developed hydraulic roller relief system enab-les grinding of different fuels (both hard and soft) and impro-ves the machine control response.
Cause Analysis of Vibration of Vertical Mill ... At the same time, too thin the material layer can lead to a rigid contact between the grinding disc and the grinding roller, which causes a large vibration, which causes serious wear of the vertical mill equipment and increases the energy consumption.
