During mill operation roller surfaces wear down, which results in a higher dynamic load, peaks which exceed the nominal torque and, in general, an instable mill operation and lower performance. In many instances, bearing failures at the rolls are caused by excessive dynamics in the grinding process. The Dalog Torque Sensor DTS 100 (Figure 6) is a direct measurement system that detects high ...
· Optimization of Cement Grinding Operation in Ball Mills.

the mill. During grinding the PSD changes progressively, hence results can differ a lot at different finenesses, energy consumption levels or grinding times. In a twocomponent system some general trends have been observed. In the early period of grinding (at low fineness), the harder component will enrich in the coarser fraction and the softer will dominate the finer fraction of the PSD. The ...

Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse silica in the feed are difficult to grind.
