Vibration Characteristics of Rolling Mill System under ...

Considering the two kinds of nonlinear constraints of rolling mill hydraulic cylinder, spring force and friction force, the vibration model of rolling mill system is established. The amplitude frequency response equations are obtained by using the average method. Comparing the time history curves of vertical vibration displacement of rolling mill system under the nonlinear spring force and ...

Cement Mill Drives | Transmission (Mechanics) | Engines

2021-2-18 · Function: A cement mill is a drive used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills. Process: Raw materials are fed to the mill in right proportion with the help of weighfeeders.
