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. From the AG mills, the ore travels to the primary magnetic separators where the iron is drawn away from the waste material before it's screened and fed into the ball mills.


Raw materials - worldsteel.org

Today, it is estimated that the global steel industry used about 2 billion tonnes of iron ore, 1 billion tonnes of metallurgical coal and 575 million tonnes of steel scrap to produce about 1.7 billion tonnes of crude steel. Recycled steel (also called scrap steel) is one of the industry's most important raw materials.


Ball Mills - an overview | ScienceDirect Topics

As mentioned earlier, pebble mills are widely used in the North American taconite iron ore operations. Since the weight of pebbles per unit volume is 35–55% of that of steel balls, and as the power input is directly proportional to the volume weight of the grinding medium, the power input and capacity of pebble mills are correspondingly lower.

Woodward Iron Company Four iron-making enterprises, each controlling substantial deposits of iron ore, coal, limestone, and dolomite, came to dominate the industry. These companies were unique in their use of advanced blast-furnace plants that smelted iron ore into pig iron. Woodward Iron, Sloss Sheffield Steel and Iron Company, and Thomas Works operated …


Vertical mill simulation applied to iron ores - ScienceDirect

Abstract. The application of vertical mills in regrind circuits is consolidated. This type of mill is now attracting interest in primary grinding applications, due to its higher efficiency when compared to ball mills, which are usually used at this stage. In this study, a coarse sample of iron ore was tested in a pilot scale grinding circuit ...
