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.

They are commonly known as ball and tube mills. It is the oldest and the most frequently used pulverizer design. As described by J. Kitto and S. Stultz, it consists of a horizontal hollow cylinder, partly filled with small diameter balls, which rotates around its longitudinal axis.The .
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.
