Chat OnlineTo minimize the roll diameter a four-high or cluster mill is used. A small roll diameter is advantageous because less roll is in contact with the material which results in a lower force and power requirement. The problem with a small roll is a reduction of stiffness which is overcome using backup rolls. These backup rolls are larger and
