Scale formation and its removal in Hot Rolling processThere are two kinds of scales relevant in rolling mills sticky and dry scales Sticky scales can be removed most effectively by use of high pressure water jets upto 450 bar Dry scales can be removed from the surface by application of descaling systems with low distances of the descaling nozzle to the material Nozzle characteristics and spray header design play a major role in the
High Pressure Roll Compactor Machine BepexThe Bepex Roll Compactor is a high pressure agglomerator able to press fine and often highly aerated solids into larger cohesive masses with controlled densities Agglomeration is performed by compressing fine material between two opposed counter rotating rolls held under pressure By utilizing high pressure to agglomerate you often eliminate the need for a liquid binder and the ensuing
