Then the iron ore pellets will sent through metallic conveyor into the furnace to undergo heating process at 1200 degrees. After the heating process, the heated base mix will converted into a semi liquid cake. Using a sinter breaker machine the cake is break into small pellets. Finally these iron ore pellets under goes cooling in the cooling tower.

1. Introduction. Iron ore pellets are one of the significant sources of iron for iron and steel making due to their superior metallurgical performance, low energy consumption, and less emission of environmentally harmful dust and gases during the production process [1], [2], [3].The two primary raw materials for pellet production are hematite and magnetite concentrates.

The sinter plant that converts the iron ore fines into a desirable blast furnace feed, offers an avenue for recycling wastes. One of the several wastes that are produced at an iron and steel plant is the undersized pellet fines, which cannot be directly used in iron making. The present study evaluated the influence of these pellet fines on the sintering process. 5 experiments were conducted ...

Intensification of the iron ore sintering process is approached with a fourway framework covering granulation improvement, waste gas recycling, fuel gas injection into the sinter bed, and reduction of stack emissions. Various metallurgical wastes are granulated to form micro pellets and are dosed along with the feed to cut down the cost.

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.
