Köppern – Specialists in HighPressure Comminution 7 Improved CostEfficiency Highpressure grinding roll presses (HPGRs) are emerging as an important comminution technology in the minerals processing industry. The technology has found its key application in the liberation of diamonds and also in primary comminution.
The specific pressure (SP) (, total force divided by projected roller area) is typically in the range of 39 N/mm2 depending on different situations, however, pressures up to 1,000 N/mm2 within the operating gap were also reported (Maxton et al., 2003). Comminution in HPGR is a result of high interparticle stresses generated when a

High pressure roller mill is used in mineral industry, building industry, chemical industry and metallurgy industry. It is used for high fineness production of more than 400 kinds of non flammable and non explosive materials of Mohs hardness less than richter scale, humidity below 6%, such as quartzite, feldspar, barite, fluorite, dolomite, garnet, carborundum, bauxite, zircon sand, marble ...
In the 19th century roller mills were adapted to grist mills before replacing them. The mill used either steel or porcelain rollers. Between the years 1865 and 1872, the Hungarian milling industry upgraded and expanded the use of stone mills combined with roller mills in a process known as Hungarian high .
The throughput of a highpressure roller mill equipped with a screw feeder depends on the roller velocity u and the screw speed n S. Fig. 9 Fig. 10 show results with the materials 2 and 3, respectively, those with the materials 1 and 4 are given in Ref. . The dashed line represents the screw throughput.

Jul 02, 2013· High pressure grinding Roller (HPGR) is modeled as a dynamically controlled body, responding to the balance of forces applied from material bed .
HPGR or highpressure 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 types, such as very hard, abrasive ores.
High Pressure Roller Mills are used in the cases of mediumfine crushing of hard materials such as ceramics, minerals from 5 up to 9 on the Moh''s hardness scale, metals and metal alloys. High Pressure Roller Mills are used in continuous operation or in a closed circuit with screening machines or classifiers.
It is known that an efficient comminution with high pressure roller mills occurs for energy saving and size reduction. One of the roller press mills available is Poittemill produced by POITTEMILL INGENIERIE Group, France. This mill combined with air classifiers has been commercially applied into powder processing plants (Wang and Forssberg, 2004).

It has the same working principle as Raymond Mill, but its grinding device is fixed with 1000 1500 kg pressure springs. When the machine works, the grinding roller, under the action of high pressure spring and centrifugal force, rolls close up to grinding ring, its rolling pressure is times higher than that of Raymond mill given an identical condition and its output may increase 20% to ...
Other designations were also used for the high pressure grinding technology with respect to a wide range of applications from coarse crushing to very fine grinding, such as ''high pressure roller crusher'', HPRC. The generic term that has been widely settled upon is HPGR, high pressure grinding rolls, and is used in this paper as well.
