iron ore sintering and pelletizing

SINTERING AND PELLETISATION OF INDIAN IRON ORES

Emission Optimized Sintering (EOS®) for lower costs Iron ore sintering creates substantial off-gas volumes, and treating these in order to meet increasingly stringent environmental standards is expensive. EOS® uses recycling technology to reduce off-gas volumes by 40 to 50 %, resulting in smaller secondary gas treatment systems. This means:
