Results of the successful demonstration are presented and evaluated in this Lone Tree HPGR demonstration plant operated for three months, from April through June 2003. The HPGR operated for 1626 hours and processed 141,000 tons of ore.
"High Pressure Grinding is applied in iron ore pellet feed preparation to generate a specific surface area increase. The technology is applied for final grinding of fine concentrates or pregrinding (ahead of conventional milling) of particles.
Nowadays, the HPGR (highpressure grinding rolls) is an intermediate step between filtering and balling in the most modern iron ore pelletizing operation. The operation debottlenecks filtering process and reduces pressure over the typical milling process to control particle size to the balling.
High Pressure Grinding Rolls (HPGR) were introduced as a new grinding technology in 1984. . have also been applied in mineral processing plants, largely in iron .
High pressure grinding rolls (HPGR) technology is growing to be a common comminution tool in iron ore processing. The technology finds a wide acceptance and presents specific benefits in coarse ore grinding and closedcircuit grinding in preparation of ball mill feed, right down to the other end of the particle size spectrum for iron ore pellet feed preparation.
