High pressure grinding rolls (HPGRs), also known as roller presses, are rapidly gaining acceptance in hard-rock processing, primarily due to their energy efficiency when applied in comminution. Today's highly competitive mining industry calls for continuously operating high throughput equipment, such as the HPGR, to be designed for maximum ...

SGS has developed a simple methodology that is based on the 0.25 m LABWAL HPGR from Polysius, which has a sample top size of 12.5 mm. Several HPGR tests are performed to assess the effect of operating pressure and moisture content on the performance of the HPGR and the power input to the unit is recorded.

Es por esto que la trituración o molienda con HPGR (High Pressure Grinding Rolls) surge como una alternativa a ser evaluada en los procesos de conminución. En este equipo el principal mecanismo de ruptura es inter-partícula, es decir, las partículas entre sí realizan fuerza de compresión directa entre ellas.

The application of High Pressure Grinding Roll (HPGR) in comminution circuits is well established in processing cement, diamonds and iron ore. Recently, the application of HPGR has been extended to high-tonnage precious and base metals operations with hard ore. This is due to the HPGR: being more energy-efficient than grinding mills, not
