high pressure grinding roll drive

Roll Grinder | MachineMfg

The linear guide rail is positioned to move the ball nut up and down to drive the high-precision static pressure biasing for small angle swing. The grinding wheel spindle in the static pressure eccentric sleeve makes a slight gap-free incision (or withdrawal) movement with respect to the roller surface.

2019-10-15 · 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....

High Pressure Grinding Roll for advanced crushing

Cardan shafts connect the main drive motors to the high-speed reducer shafts via torque-limiting couplings. These torque limiters are manually-engaged and critical for protecting the drive and HPGR components in the event of an overload situation. Rigid drive couplings attach the reducer output shafts to the roll shafts completing the drive system.
