Mining Magazine > Panorama > Weir teams up with KHD

Weir Minerals has been appointed as KHD Humboldt Wedag International's exclusive worldwide agent and recommended service provider for high pressure grinding rolls (HPGRs) for mineral processing applications.

High pressure grinding is achieved using an advanced type of grinding roll. The particles are broken by compression in a packed particle bed, and not by direct nipping of the particles between the two rolls, as in conventional crushing. KHD is an originator of this technology and has been successfully marketing HPGRs in mining market since 1986. Using HPGRs has been shown to improve throughput while also decreasing operational costs and power consumption especially when compared with a traditional SAG mill.

"Working with Weir Minerals in the mining marketplace was an easy decision," says Ekkhart Matthies, KHD’s comminution director. "Their reputation and relationship within the industry are superb. They will help the KHD roller presses increase their presence and reach in minerals processing facilities worldwide. This also combines our leading technology with a world class service provider and hence significantly improves our offering to customers."

Scot Smith, MD of Weir Minerals comments: "We are delighted to be working with a company of KHD's outstanding reputation and dedication to quality. Offering the KHD HPGR extends our portfolio in mill circuit and minerals processing operations around the world, and will allow us to further our relationships and commitment to our customers."
