Ball Technology For Iron Ore Fines

melting and sintering coarse iron ore 1 to 3mm in size into products having a size of 15 to 30mm. The sintering process uses the combustion heat of coke breeze (fuel). Pellets are made from iron ore that is finer than that used for sintered ore. The ore fine is formed into spheroids, called green balls, approximately 12mm in diameter.

Iron ore fines (0.1 – 2.0 mm) are dried and preheated in a CFB preheater up to 900 °C before being introduced into the first-stage CFB reactor for the primary reduction stage. Fast prereduction to a reduction level of up to 80%. Final reduction in bubbling FB reactor achieves reduction degrees in …

In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.

The required P 80 of the ore, in order to achieve adequate liberation, is 40 μm. This plant uses a vertical stirred mill after AG rather than a ball mill to achieve this fine grind size with an energy cost saving of 35% or better (Arvidson, 2013). An important part of the comminution circuit is size classification.

The grinding is achieved by impact, creating coarser particles, pinching or nipping giving smaller particles, and abrasion generating fines. Grinding is often finished with a ball mill, which differs from a SAG mill, as it relies on the steel alone for grinding. A SAG mill may have 10% steel where a ball mill will typically have 30%.
