Choosing vibration monitoring methods - Applications

These mills are characterized by their large diameter and short length, as compared to ball mills. The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge.The monitoring of this type of equipment is crucial for modern mining operations.
