In China, the pellet is usually produced by the grate-kiln process, and all the required heat in the process is provided by burning coal or fuel gas in the rotary kiln. Meanwhile, there is a large amount of air sucked into the kiln to make the pellets oxidized, and the air can be heated to temperature above 1300 °C [ 3 ].

The dominant process adopted to produce iron ore pellets in China is the grate-kiln process [10–12]. The preheated pellets roll in the rotary kiln and can be sintered uniformly; therefore, it is known that the grate-kiln method yields a superior and more consistent pellet quality compared with the straight-grate process [13].
