Our heavyduty iron ore balling drums are relied on by some of the industry's top producers to process iron ore fines into pellets for the steelmaking process. The use of a disc pelletizer is a popular alternative approach to pelletizing iron ore fines, as this offers more control over pellet size and produces a more refined pellet product.
Declining ore grades, fine grade ores and the environmentally sustainable use of water are major challenges facing not just the iron ore industry but, increasingly, the entire mining industry as well. It needs energyefficient grinding circuits to offset increasing costs. The polycom ® dry finish grinding concept in combination
The crushed iron ore is then processed above ground to either fines or iron ore pellets. It is a complex process that takes place in several stages: Sorting: The ore is roughly sorted and residual waste rock removed. After that, the iore ore is crushed into smaller fractions. This increases the iron concentration from approximately 45 to more than 60 percent. .

· Iron ore and iron ore pellets are important sources of iron for manufacturing steel. The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries, such as China and India. However, the content of iron ore in deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting .
· When the iron content in the processed iron ore contains more than 60%, which would generally be the lumps, they are shipped directly to the plants. Iron ore fines are considered less desirable as they need to be sintered first (so as to not to smother the air flow in the blast furnace) before they can be utilised for the blast furnaces. According to industry .
· Every 24 hours, around 180,000 tonnes of ore are fed into the six milling lines' autogenous grinding mills (AG mills), these are the largest grinding mills in the world. Each mill measures about 12 metres in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart.
