Understanding Sinter and Sinter Plant Operations – IspatGuru

 · Use of sized sinter is desirable for the improvement of production rates in the blast furnace. Further, crushing the sinter to 30 mm size at the sinter plant yields a more stable sinter because the smaller size fractions are more resistant to degradation. A supervisory station controls all steps of the sintering process.
