Singleroller mill. 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 ...
Rolls are tools used in rolling mills to reduce the cross section of metal stock. The weight of rolls may vary from a few kilograms up to 250 tonnes. Under rolling conditions the contact area between roll and stock suffers wear, the other parts of a roll
