High Pressure Grinding Roll Features amp; Performance. The high pressure grinding roll has established itself in various industries. High pressure grinding rolls has been leading the way for the use of HPGR in the nonferrous metals mining industry. In comminution circuits of the cement and diamond industry, HPGR has become a standard grinding tool.
Dec 15, 2002#0183;#32;In the United Kingdom, engine maker RollsRoyce has responded to this challenge with a process that achieves flexible grinding of nickel alloys using grindingwheelequipped machining centers. The process goes by the name quot;Viper,quot; which is RollsRoyce''s acronym for quot;Vitreous Improved Performance Extreme Removal.quot;

TheHigh pressure grinding rollhas two opposite directionsrotating rollers forming a nip between them,in which the ground material is drawn in and comminuted under high pressurebecomes. The...
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.
High Pressure Grinding Rolls (HPGR) is a mature technology that is proven to reduce capital and operating costs in full scale plants when compared to other comminution technologies. Read more SGS comminution experts have developed a simple testing methodology to avoid some of the difficulties associated with using HPGR.

This places it in the fourth quartile of the cobalt and nickel cost curve. The major cost at the operation is from the processing plant where the ore is not suited to semiautogenous grinding, relying instead on a more expensive highpressure grinding roll. Although the project is high cost, balancing that is its sustainability credentials. Nickel from sulphide deposits such as Turnagain have
