Product Description
High Pressure Grinding Rolls (HPGRs)have been applied in mineral processing plants, largely in iron ore and diamond treatment. In these industries, the application of HPGR ranges from coarse grinding, e.g. the grinding of 65mm (2.5")size excess pebbles in circulation loops, to final grinding of <100μm material to high Blaine values in the preparation of pellet feed.
HFKG High Pressure Grinding Rolls (HPGR) offers several benefits to the minerals industry, such as:
Low energy consumption, 0.8-3.0kWh/t
Ability to process moist ores, up to 10%
Enhanced downstream recovery and grind ability
Improved grade of downstream products
Low maintenance requirements
Low space requirements
Low vibration and noise
High availability, >95%
High wear surface life, 8000-36000 hrs
