Screening equipment is installed after the primary crusher, after the scrubber and after the tertiary comminution stage to separate the iron ore into a dry coarse fraction (8 40 mm) and a wet fine fraction (> 1 < 8 mm). The fraction < 1 mm passes through another washing stage.
WhatsApp: +86 18037808511Abstract The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the highgrade ores depleting very fast, the focus is on the beneficiation of lowgrade resources.
WhatsApp: +86 18037808511In the Blast Furnaces, we melt iron ore into liquid iron at high temperatures. Iron ore has a sandlike structure that can put out the fire in the furnace. Because of that, you can't put it in the furnace just like that. The ore is first baked to make it into porous chunks, or sinters. This is done in the Sintering Plant. In the Pelletising ...

WhatsApp: +86 18037808511The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process ...
