    2019-4-10 · The OK mill uses a hydro-pneumatic system to press its grinding rollers against the material bed on the rotating grinding table. Segmented roller wear parts are made of the hardest possible material that do not crack and are very well-suited for repeated hard-facing. Re-positioning of rollers is possible to distribute wear more evenly.
