Blended cements can be produced in two ways: by intergrinding the components or by separate grinding and mixing them. With the intergrinding process all components of the blended cement are ground together. In that way the cement is homogenized during the grinding, and at the concrete plant only one silo is needed.

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 D-TS 100 (Figure 6) is a direct measurement system that detects high ...
