FLENDER gear units for roller presses


Between two contra-rotating rollers, dry small-grained material is subjected to a high specific force of pressure. In roller presses, fine-grained materials are either pulverised or compacted into uniform bodies or plates. If used in the cement and mining industries (copper, gold, diamond mines, etc.), roller presses serve to reduce materials in size and, as a rule, they precede other mills. In all areas, customers rely on proven drives such as FLENDER planetary gear units and FLENDER gear units.
