Upper and lower working rolls 2a, 2b are ground while moving respective grindstone devices 3a, 3b in reverse directions, whereby the region of grinding for the upper working roll 2a and that for the lower working roll 2b are maintained in symmetry with respect to the center of rolls, one on the operating side and the other on the driving side.

Smooth or profiled rolls can tolerate larger sizes – however at the expense of wear. For optimum grinding effect, the rolls should be choke-fed. Underfeeding the rolls re-duces breakage and causes excessive wear at the center of the rolls. Misconception 4. "It is more efficient to grind truncated feed than full feed size distributions".
