The traveling grate is a kind of crawler-type thermal equipment, used for drying and preheating green pellets in iron ore pelletizing plants. It is comprised of chains that can convey pellets like a conveyor belt. While the difference is that the traveling grate allows hot air to pass through during the uniform transmission.

The traveling grate is usually placed before the rotary kiln to make full use of waste heat of the annular cooler and the hot gas discharged from the rotary kiln for drying, preheating, oxidizing, and solidifying the green pellet, and then sending the green pellet to the rotary kiln for further induration. It forms the grate-kiln system together with rotary kiln and annular cooler, which is an important part of the iron ore pellet production line.

After entering the traveling grate, green pellets (8-16mm) are evenly laid on the grate plate according to the required material layer thickness. Then, the grate plate carries the green pellet and moves towards the direction of the discharge port at a uniform speed.

Generally, the traveling grate is divided into blast drying area, exhaust drying area, and preheating area. Green pellets will first enter the drying section (300-550 ℃) to remove the moisture inside, then get into the preheating section (750 ~ 950 ℃) for further dehydration and produce a redox reaction so that the green pellet has a certain compressive strength. After that, the green pellet will be discharged from the outlet port and fed into the rotary kiln for induration.
