Iron ore pelletizing Grate-KilnTM system

The refractory lined rotary kiln performs the induration and creates a mixing of the material bed and complete mineral brid-ging of the green balls into heat hardened pellets. The kiln also gives a robust firing chamber for combustion of fuel. The rotary kiln is a downwards sloping cylinder from the traveling grate to the annular cooler. The
