With the singleroller mills, brittle, soft to mediumhard materials can be reduced in size with a reduction ratio of approx. 1:5 to 1:5. The stepped arrangement of the crushing jaws on the crushing wall enables any material rolling off being minimised, so that, compared to the doubleroller mill, coarser material can be drawn in.
