Pressure Feeder Roll Mill

Troubleshooting roll defects - causes and corrective actions

Non-uniform nip pressure: See above. Crushed roll. Sometimes called a "baggy sock roll" and is the result of stacking rolls on end in an excessively high pile which in turn causes the lower rolls to fail in an axial direction. Excessive axial pressure: Stack rolls to a more conservative height. Winding too soft: Wind rolls harder. Dished roll

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.

High Pressure Roll Compactor Machine - Bepex
