Pellet
In the mining and steel industries, a Pellet refers to hard, spherical pellets produced from iron ore fines. These pellets typically have a diameter between 9 and 16 mm and are used as feed for direct reduction furnaces or some blast furnaces.
How are pellets produced?
-
Grinding and crushing iron ore → Conversion into fines (powder)
-
Adding additives such as bentonite (binder) and water
-
Ball formation in disc or drum pelletizers
-
Induration (hardening) at high temperatures to strengthen and harden the pellets
Why is pelletizing important?
-
High mechanical strength for transportation
-
Suitable porosity for better reduction in the sponge iron production process
-
Uniform size, which leads to stable furnace operation
-
Improved productivity and reduced energy consumption in furnaces
