Abstract: Highpressure grinding rolls (HPGR) have gained great popularity in the mining industry in the last 25 years or so. One of the first successful applications of the technology has been in iron ore pressing prior to pelletization. Pistonanddie tests can provide good insights on the material response in an HPGR.
NRRI obtained the HPGR technology from the Magnetation operation, which has been closed. Both groups will share maintenance costs. According to NRRI and , 53% of a mine site''s energy consumption is attributed to crushing and grinding ores, which is .
HPGR technology was introduced to the mineral processing industry in the mid1980s and has rapidly (for the mining industry) established itself as the convention in the comminution of cement, clinker, slag, iron ore, iron pellet plant feed, and diamond ore. There are now approximately over 500 machines operating in these applications.
