Sintering of agglomerate during separate preparation of the charge

The paper presents the results of research into a common and separate method of preparing a charge for sintering agglomerate. The best quality of the agglomerate was ensured by separate lumping of the “concentrate-ore-limelimestone” composite, the basicity of which was 0.9-1.0 units, and the residual charge with the basicity of 1.6-1.8 units, after which both composites are mixed in parallel. Then their joint granulation takes place. Fuel is supplied at the end of granulation. Sintering of the agglomerate prepared by the proposed method allows to increase the yield of suitable agglomerate by 10.25 % and to reduce the content of the 0-5 mm fraction after the strength test by 11 %.
