Used in mining applications for the last 30 years, High Pressure Grinding Rolls (HPGR) reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them.
High chromium white cast iron alloy used in coal grinding components is a material that may present different wear resistance depending on the thermal treatment used in its manufacturing.
Nov 15, 2017· There are many reasons for corrosion and wear in mill roller shells. such as rust of metal mill rollers (as a result of the presence of acidic juice); friction between the top scrapertrash platecane sucker and mill rollers; and on top of all the high speed of the moving rolls, where the wear in the middle of the mill rollers is greater than their ends.
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 grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.
To reduce In terms of energy consumption, the socalled good bed roller mill has been developed. The High pressure grinding roll has two opposite directions rotating rollers forming a nip between them, in which the ground material is drawn in and comminuted under high pressure becomes.
