Dear All, We have a Midrex Sponge Iron plant producing cold DRI. Since some days we are noticing fire in DRI dust. The temperature stays normal at the furnace discharge but when the product gets transferred after moving through a belt for around 200 meters to another belt the DRI dust catches fire. It is happening again and again. We have started using some new pellets since some days but most ...

The Brazilian iron ore resources are shifting from high grade ores with good liberation at coarse sizes, to lower grade ores with good liberation only at finer sizes, requiring grinding down to a fine size to liberate and concentrate. Considering the very large throughputs required in the plants it is important to ensure the long-term economic and energy feasibility of this process.

SAG mill is usually used to grind large pieces into small pieces, especially for the pre-processing of grinding circuits, thus also known as primary stage grinding machine. Based on the high throughput and coarse grind, AG mills produce coarse grinds often classify mill discharge with screens and trommel.
