As regards “abnormal” rolling conditions which are more or less very “normal” for rolling mills roll damage often occurs with consequences for the mill and the rolled product. Evidently the reasons of roll failure have to be discussed and determined (or vice versa)
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.
