The width of the grinding rollers are far greater than the arc length of the compaction zone in the circle view direction of the roller, and the actual wear of the mill roll surface also appear in the width direction. Therefore, it is helpful for analyzing the load distribution in the width direction of the grinding rollers, to clarify the state of mill work, and understand the non-steady
