Roller Presses are used when grinding pressure is needed to be 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 agent. Alternatively, grease lubrication is possible. Power transmission from the electric motors is effected via cardan shaft, fluid or safe set coupling and clamping disc fitted gear boxes, usually of planetary design. Depending on the application, the rollers are either one piece solid construction or shaft and tire design with suitable wear protection for almost all applications in the cement and minerals industry.

Common Features

  • Generously sized bearing load factor
  • Continuous feeding of filtered lubrication oil
  • Bearings cooled by the lubrication oil for low bearing temperature
  • Bearing sealing with fixed radial shaft sealings arranged back to back
  • Additional permanently greased labyrinth with V- ring and separate dust
  • labyrinth on the inner side of the bearings.
