HPGR is an energy-efficient size-reduction comminution device used in mineral processing industries since the mid-1980s because of its unique ability in energy reduction ; improved gangue-mineral value liberation ; induction of micro-cracks at the grain-boundaries, which ultimately results in higher grade; and recovery of mineral values in …
The HPGR is considered as a mill or crusher, depending on the flowsheet needs or the nature of the material. The mass balance in this type of comminution device is simple, requiring only a breakage function and a selection function to describe it. Nevertheless, all models include a material properties description function, which is the ...

It has been known that the performance of high-pressure grinding rolls (HPGR) varies as a function of the method used to laterally confine the rolls, their diameter/length (aspect) ratio as well as their condition, if new or worn. However, quantifying these effects through direct experimentation in machines with reasonably large …
The machinery used for model validation consists of two robust devices. The first is an industrial type of machinery, of 1 m diameter with 0.23 m wide rolls (Fig. 2).The other is a lab-scale type of the same machinery, and has a diameter of 0.03 m and 0.07 m wide rolls.Both models have studded liners for the roller surface, and use four …

Our HPGR is a perfect complementary tool to work in conjunction with, and even enhance the performance of traditional grinding mills and fixed-gap crushers. The HPGR exposes feed material to very high pressure for a short amount of time. The compression typically causes the rock to crack and cleave along the grain boundaries, weakening the rock ...
HPGR. HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case …
Increase the speed of the rolls to raise the HPGR throughput. Decrease the speed of the rolls to lower the HPGR throughput. Increase the press force for a finer HPGR discharge. Decrease the press force for a coarser HPGR discharge. FL has more than 70 roll presses installed worldwide High pressure grinding roll

The whole ore sample is used to determine the F. 80 and the minus 6 mesh product from the last cycle is used to determine the P. 80. The average specific energy for the last. 3 cycles is now used to calculate the locked cycle HPi, similar to the Bond Work Index value, where: = 10 * HPi * (√(1/P 80) - √(1/F. 80))
