According to the raw material characteristics of high-titanium type vanadium-titanium magne-tite concentrates , such technical measures are taken as optimizing the process parameters , reasonably controlling the contents of sintering ore , using plaid lining and ladder funnel in finished ore transporting and screening system , lowering belt speed , adding b buffer overflow chutes for BF ditch screen , narro-wing sieve aperture , reusing the particle-grade sintering ore from BF , the rate of returned sintering fines of high-titanium type vanadium and titanium concentrates is reduced , and a great role in optimizing the ore structure of BF has been played under deteriorated material condition .
