Research on the Quality Improvement and Consumption Reduction of Iron Ore Agglomeration Based on Optimization

In order to increase agglomeration production and improve its quality while reducing energy consumption, a new intelligent blending method has been established at Ansteel optimize sinter blends. The statistical model of the ore results shows that (1) ratio 47.2% Ore A 52.8% C corresponded best yield 72.44%. (2) From viewpoint reducibility, basicity should not be less than 1.98 when proportion in blend is more 35%. Due low mixing efficiency disc pelletizers, therefore gone through massive technical transformation Sinter Plant 3 replace 16 existing pelletizers with one drum granulator. Since installation granulator, standard deviation decreased from 1.517 0.7332 for total Fe (T.Fe) 0.146 0.0956 basicity. case T.Fe were 0.6926 0.05449, respectively, as compared 0.8902 0.2033 pelletizers. addition, single lattice proposed particle-size distribution coke breeze further reduce fuel consumption. indicated optimum achieve maximum tumble strength consist approximately 57.20%: −1 mm, 25.63%: 1–3 11.17%: 3–5 6.00%: >5 mm particles. Given international trend increasing bed depth, successfully achieved height 1050 or under conditions, which typically contain 75% concentrates. Finally, some iron agglomerations research discussed.
