  • A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING

    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) to reduce the risk of repeated roll Mixing mills DEGUMA-SCHÜTZ GmbH,The two rolls of the rolling mill rotate in the opposite direction. For the purpose of mixing, one roll runs faster than the other one (friction). Therefore, shearing forces act on the rubber in the nip between the two rolls. In this way, the rubber is mixed.
