adds a fifth roll at the bottom of the tube, allowing smaller diameter side rolls to be used. Many smaller mills use three rolls mounted 120 degrees apart. Some are orientated with a grooved roll at the top of the tube (D), others with a roll directly below the tube. D eliminates edge misalign-ment and is especially suited to D/T ratios above 10:1.

A good maintenance program, as well as rebuilds or upgrades when necessary, is essential. 6. Mill in misalignment.
