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.
THE MECHANICS OF TENSION CONTROL
Roll diameters are constantly changing, so torque and speed must be constantly adjusted relative to changing roll diameters. Tension and speed in the internal zones is much more stable since roll diameters in these zones does not change. However, some control is required to set and maintain desired levels.
