Grinding between rotating rollers An Enduron® HPGR reduces particles by compressing and grinding the feed between two counter rotating, parallel rollers. This forces the rocks against each other and compresses the feed's density to 85% of its solid volume. This compression is achieved by applying high pressure of up to nearly 300Mpa ...

The high pressure comminution process causes micro-cracks in the particles, which lead to the liberation of minerals and a higher portion of fines. HPGR treated minerals show better leaching performance, because the micro-cracks increase the particle contact surface for the leaching liquid. Also, flotation efficiency is further enhanced through ...
