High pressure grinding rolls HPGR Metso Outotec
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.
POLYCOM high pressure grinding roll.
The mill feed mat-erial can be dry or moist with a largest feed grain size of up to 60 mm. The POLYCOM can be used as a primary mill in combination with – for example – tube mills, as a component of combi grinding systems, or as an independent finishing mill. The larger the amount of grind-ing work performed by the high-pressure grinding ...
A Review of the Modeling of High Pressure Grinding Rolls
Sch nert tended to call the technology either “high com-pression roller mills” or “high-pressure roller mills”, HPRM. 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 grind-ing, such as ‘high pressure roller crusher’, HPRC. The ...

High pressure grinding rolls HPGR applications in the
Feb 01, 2006 1.. IntroductionSch nert (1979) has shown that the most energy efficient method of comminuting particles is to compress them between the two plates. Compressing a particle bed between two counter rotating rolls was achieved by the invention of the high pressure grinding rolls (HPGR) (Sch nert and Knobloch, 1984).The first commercial application of HPGR was in 1985 and its success …

ROLLING A Brief Guide To Rolling And Rolling Mills
Generally, they are two high reversing mills (24-54-inch diameter rolls) For high production rates, universal mills are used to take care of edging (two vertical rolls to control the edge). High-pressure water jets remove scales. Subsequent to the last finishing stand, strips are sheared to the required size or coiled to obtain continuous sheets.
