Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite, hematite, goethite, limonite or siderite.VERTIMILL® is ’s gravity-induced, vertical stirred mill. Its vertical configuration allows for large throughputs while maintaining a small footprint in your circuit. The VERTIMILL® can bring up to 40% savings in energy consumption in some cases, and helps in reaching excellent recovery rates by producing a sharper particle distribution. VertimillsVertimill® HIGmillTM Stirred Media Detritor (SMD) Vertimill® The Vertimill® is globally recognized as an energy eficient grinding mill. Through a low total cost of ownership, it brings substantial improvement to the profitability of concentrators.Stirred mills - احصل على السعر
