High Pressure Grinding Rolls in the mining sector
The Weir Group PLC (Weir) and KHD Humboldt Wedag International AG (KHD), announce that Weir Minerals has been appointed as KHD’s exclusive worldwide agent and recommended service provider for high pressure grinding rolls (HPGRs) for minerals processing applications.
High pressure grinding rolls, also called roller presses, have been used in the treatment of iron ore, copper (Fig.), gold, diamond and various other ore types for many years. Contrary to conventional crushing rolls, the particles are broken by compression in a packed particle bed, and not by direct nipping of the particles between the two rolls. KHD is an originator of this technology. Using HPGRs has been shown to improve throughput while also decreasing operational costs and power consumption especially when compared with a traditional SAG mill. Weir Minerals is a global leader in the minerals processing and mill circuit venues with their Warman® centrifugal slurry pumps, Cavex® hydrocyclones, Isogate® slurry valves and Vulco® wear resistant linings, as well as their outstanding service offerings. Weir Minerals sales and service representatives will begin representing this portfolio extension to their clients in the mining sector immediately.
