What is Roll Roughness? 5 Roll Ra's and Why They Are Important
Five Different Roll Roughness's. 1. Flaker Rolls (130-150) Roughness is an important characteristic of flaker rolls during the seed oil production process. When seed oil is processed through a set of rolls, they are flattened and sheared to an ideally thick flake. If the flake is too thick, all the oil cannot be removed from the bean.

Where, is given by: (h. o +h. f)/2 . 1.4 Roll torque and power: Roll torque can be estimated from the rolling force. Torque is equal to force multiplied by the radius at which the force acts. We can assume that the roll force is acting perpendicular to the strip at a radius equal to one half of the projected arc lengt h of contact.
