As the grindability of the feed materials increases, so does the effi-ciency of the high-pressure grinding – and the polycom ® reveals its full potential. In these cases, compared to a roller mill, up to 20 percent of the energy required for grinding can be saved; com-pared to a conventional ball mill, savings of up to as much as 50
An HPGR with a brand new set of rollers starts opera-tion with identical torque and speed. Over time and based on various operating factors (e.g. ore character-istics, operating pressure, feed etc.), the rollers experi-ence different wear rates. With RollXtend the load pro-vided by both rollers can be fine-tuned by the operator
industries, the application of HPGR ranges from coarse grinding, e.g. the grinding of 65mm (2.5") size excess pebbles in AG circulation loops, to final grinding of <100μm material to high Blaine values in the preparation of pellet feed.

In case of the HPGR the optimum point of operation is widely influenced by ore properties like feed size, hardness and the rate of feed. Energy cost and water savings, smaller plant footprint and extended availability are some of the main reasons why we see more and more HPGRs within crushing and grinding circuits.
CLM series HPGR is widely applied in metallurgical mines and chemical industry etc. It is a kind of grinding equipment designed based on the principle of material bed communition, mainly consisting of frame, roller assemblies, hydraulic system, feed gate, control system, transmission system and other components.

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 for certain ore ...
The coarser feed size corresponding to the HPGR #4 is consistent with its pre-grinding role in the circuit. The feed size distributions of the feed to HPGRs #1 and #2 are finer and consistent with the regrinding pre-pelletizing role of the machines downstream from ball mills operating in closed-circuit.
24/17 High Pressure Grinding Rolls (HPGR) Installation Hours. ... Where equipment is received as a shop assembly unit, alignment shall be checked and adjusted where necessary. ... Moving the two rollers into the press frame is done using the roller pulling device to move the rollers into place in a parallel motion.
The HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure grinding process. The machine reduces particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them.

If HPGRs are operated correctly, ball mills can be downsized and use smaller grinding media, which substantially reduces steel ball consumption, increases the grinding efficiency and lowers operating costs of the milling substantially. The use of HPGR technology also promotes micro fracturing, which can expose minerals encased or locked within a particular ore.
