The Aerodynamics of an Iron Ore Pelletizing Rotary Kiln MDPI

The Aerodynamics of an Iron Ore Pelletizing Rotary Kiln MDPI

The pelletizing process, where the crude ore from the mine is upgraded, involves several steps, including grinding, balling, and induration; see Figure 1 to the left. In the gratekiln induration process []—see Figure 1 to the right—the sintering is mainly taking place in a rotary kiln, where the pellets increase their strength and metallurgical properties.

Process. Direct reduction processes can be divided roughly into two categories: gasbased, and coalbased. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
