Operating out of tram or parallel and trying to make a fine grind or thin flakes may cause the "close" end (or center of the rolls if out of tram) to actually make metal to metal contact. If the roller mill is operated with the rolls out of tram or out of parallel, significant thrust loads may be exerted on the rolls and bearings.
