Condition monitoring (or, colloquially, CM) is the process of monitoring a parameter of condition in machinery (vibration, temperature etc.), in order to identify a significant change which is indicative of a developing fault.It is a major component of predictive maintenance.It has emerged as an important technique in manufacturing industries for predictive maintenance and on-line monitoring ...
Mills in Cement Plants, Power Plants and Mines. In industry, there are different types of mills, e.g. the vertical mill, the ball mill and roller mill. Usually mills are powered by one or more electric motors. For speed reduction one or more gears are used, which in turn may contain spur gear stages, bevel gear stages and planetary stages.

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.
