High Pressure Grinding Roller Presses - KHD

With our Roller Presses, the grinding pressure is transferred from the hydraulic system via the movable roll to thematerial bed and absorbed in a stable, closed machine frame. A key feature is the mounting of the rollers in oil-lubricated cylindrical roller bearings. The oil is both, lubricant and cooling agent. Alternatively, grease lubricationis possible. Power transmission from the electric motors is effected via cardan shaft, fluid or safe set coupling andclamping disc fitted gear boxes, usually of planetary design. Depending on the application, the rollers
