ball mill pinion vibration analysis machinery

I have an issue with a gear drive on a ball mill. 2XGM is rising and i have sidebands at 107cpm and I don't know why they are at 107 (not relevant to any turning speeds ect.) I checked the root clearance a week ago and the inboard is about a .066 smaller than the outboard. The pinion is 24" long and has 24 teeth. It is obvious i have misalignment.And there is obvious spalling on the gear faces

Vibration Ball Mill Details. Vibration ball mill, also known as a vibrating ball mill or vibratory ball mill, is a kind of ball mill machine that uses the high-frequency vibration of the cylinder to make the grinding medium in the cylinder impact the material by inertial force. Vibration ball mill is a new type of high-efficiency and energy-saving grinding equipment

Mill chatter in tandem cold rolling mill is a major rejection to the quality and production of the strips. In most mill vibration models, either the roll mass is usually limited to vibrate in vertical direction and vertical-horizontal directions, or the multiple rolls system is simplified to a single mass system. However, the torsional chatter is also a typical type of mill chatter, and the

Jul 25, 2019 · Abstract. A ball mill, which is used to finely grind materials, causes high levels of vibration and sound during grinding operations. The vibration and sound of mills provide significant information about the internal conditions and can be used to estimate the status of the ground material. We developed a simulation model for the vibration of a mill wall to better understand the relationship …
