Document Type and Number:
WIPO Patent Application WO/2023/045727
Kind Code:
A1
Abstract:
A system and method for preparing a sintering fuel at a fixed scale. The method comprises the following steps: 1) performing coarse screening on a sintering fuel to obtain an on-sieve coarse-grained fuel and an under-sieve fine-grained fuel; 2) crushing the on-sieve coarse-grained fuel to obtain a crushed fine-grained fuel; and 3) performing fine screening on the under-sieve fine-grained fuel and the crushed fine-grained fuel to complete the separation of a fine powder fuel, so as to obtain the sintering fuel satisfying particle size requirements. According to the process, a sintering fuel can be produced and prepared according to set particle size requirements, the influence of fine powder in the fuel on a sintering processing can be eliminated, the combustion efficiency and utilization rate of the fuel can be improved, the solid fuel consumption during sintering can be reduced, the air permeability of a sintering material layer can be improved, and the yield can be improved.
