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 ...

Finding failure  International Cement Review
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 ...

A cement mill (or finish mill in North American usage) ... The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultrafine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet. The proportion of the millexit material ...
