Establish the Load Distribution Model for Vertical Mill ...

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 ...


Roller Mill Maintenance00 - CPM

Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.
