Cement Kilns: Size Reduction and Grinding

The elementary roller mill has a number of defects in comparison with flat stones: the material does not naturally progress from inlet to outlet, and flowable materials tend to move out of the path of the approaching roller in a bow-wave movement. The bed of material in the grinding path has to be prepared so that it can be captured in the nip of the roller. In practice, scrapers and brushes ...
