Iron ore sintering is one of the key steps in the ironmaking process, where granulated pellets are transformed into sinter in the sintering machine, providing an ideal raw material for ironmaking blast furnace. Drum granulation in the sintering process plays an essential role in determining the final sintering performance.

Blast furnace The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron.
