High Pressure Grinding Roller Presses

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

High Pressure Grinding Roll Technology,HPGR for Ore

2018-1-25  High-pressure grinding roll (HPGR) has its genesis in coal briquetting in the early twentieth century, but it was not until the mid-1980s that it was adopted for comminution applications, when it was applied in the cement industry to treat relatively easily crushed materials.. Generally, the primary motivation for the use of the HPGR as a comminution alternative is its energy ...
