With their high throughput and capacity for dealing with competent ores, High Pressure Grinding Rolls (HPGR) make ideal pebble crushers. The Enduron® HPGR’s low operating costs (owing to its long component wear life and low specific energy requirements) makes it a competitive inclusion in pebble crushing circuits, offering short payback times.

12 March 2015. It has now been several decades since the high-pressure grinding roll (HPGR) made its debut in mineral processing from its cement-based origins. With a number of hard-rock mining applications in large concentrators now several years into production, the time has come to break away from the concept of simply using HPGR in minerals

: Jhon Mendoza G.HPGR technology is a qualified alternative for large-scale comminution circuits and is becoming increasingly popular. The technology's working principle is that two counter-rotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls. Interparticle comminution is the HPGR specific

The high pressure of HPGR’s “bed-breakage” creates micro-cracks in the ore, promoting improved mineral recovery at coarser size fractions. This means less leaching acid is required and percolation periods are shortened, reducing costs and maximising recovery in less time. In the diamond industry, the HPGR acts as a selective grinder
