Solutions to abnormal vibration during rod mill operation. The rod mill is a kind of grinding equipment designed with the grinding body in the barrel as the main force. It is a kind of equipment that can meet the high granularity requirements of the finished product. The rod mill can be dry-grinded or wet-grinded according to the working form.

Vibration monitoring can provide important feedback so that the mill operation can be optimized and extend reliability. Excessive vibrations can be the result of poor mill condition. Component deterioration can include roll and table surfaces, roll and table bearings, roll load springs, and gearbox bearings and gears.

Non-center cutting end mills have cutting edges only on the sides and are used only for side milling. These tools are identified by a small hole at the center. Roughing end mills have serrations in the teeth to quickly remove large amounts of material without creating vibration. The serrations produce many small chips and a rough finish.

The vibration signal analysis for lab model sag mill is same as that of ball mill, but the frequency of operation of vibration signal and impact strengths are different [8]. Sag mill will require a higher value of g and BW of the sensor due to higher stiffness compared to that of ball mill (as the length of the mills is accounted).
