POLYCOM Ž highpressure grinding Кб. The larger the amount of grinding work performed by the highpressure grinding roll, the greater is the energy selfaligning roller bearings, which compensate for tilting of the rolls, have a multiple seal system to .
High pressure grinding roller (HPGR) equipment is a modern energyefficient comminution technology. The high pressure generates a substantial amount of fine material as it causes the boundary weakening in the feed material and formation of microcracks.
High Pressure Grinding Rolls (HPGR) The high pressure comminution process causes microcracks 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 microcracks increase the .
high pressure is applied to the bed of material in a highly controlled manner. This consistent high pressure sets the stage for more efficient size reduction downstream, by creating microcracks in the ore. Tiny microcracks weaken the particles, so that – even if the ore is not shattered – subsequent fine grinding requires the use of less energy
About 500 highpressure grinding rolls (HPGRs) are in use in the cement industry for the pretreatment of ball mill feed. This technology enhances the capacity of the downstream ball mill and reduces the total energy consumption of the grinding process by up to 50 %.

To make the mill more efficient, some roll mills are equipped with a system allowing to garantee a high pressure (1050 bar) in between the rolls. It is also mandatory for these mills to have a spring system allowing to release the pressure if the constraint is too important (foreign body for example) and avoid mechanical damages.

Such a continuing improvement of the roll surface design leads to a prolonged roll surface wear life. An example of improvement between roll set #2 and roll set #3 is show in Figure 4. This illustrates that for a wear of 16 mm on the studs, the roll set #3 could treat 3 Million tons additional ore [Barrera, 2005].
the ore body, equipment was selected to handle only 1 to 2 kg of broken ore sample in a static pressure mode rather than continuous throughput. A conventional 50 ton workshop hydraulic press was selected, as shown in Figure 1 that can apply high pressure in a controlled manner to the ore confined in a cylinder. A steel cylinder of 100mm
