High Pressure Grinding Roll (HPGR) is a modern and energyefficient surface area and pore volume of HPGR and jaw crusher comminuted products. The results indicate that HPGR products have lower work index, higher specific surface area and pore volume than its counterpart. Therefore HPGR is capable of lowering the energy consumption on plants, as well as improving the utilization of bauxite.
