When the high-pressure grinding roll is combined with a ball mill, the polycom achieves energy savings of up to 40 percent in com-parison with conventional ball mill systems. In the case of existing plants, output can be increased by more than . 6 .

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. This forces the rocks against each other and compresses the feed's density to 80% of its solid volume, exceeding its ...

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 roll, the greater is the energy saving. Modern, user-friendly regu-lating, monitoring and control devices, combined with advanced process technology,
