  • Roller Presses

    High pressure grinding. with our roller presses, the grinding pressure is transferred from the hydraulic system via the movable roll to the material bed and absorbed in a stable, closed machine frame. a key feature is the mounting of the rollers in oillubricated cylindrical roller bearings. the oil is both, lubricant and cooling.

  • Selection And Operation Of High Pressure Grinding Rolls

    It is also shown that increasing the applied grinding force reduces the bond work index of the rolls product and hence the energy required for any subsequent comminution. using a computer simulation model of a comminution circuit incorporating a high pressure rolls in pre-grinder mode ahead of a ball mill, it is shown how the specific energy consumption of the rolls, ball mill and overall circuit changes as the applied grinding force of the rolls.
