The fuel plays an important role in the sintering process, the particle size of the fuel has great influence on the sintering process, if the particle size is too coarse, the combustion rate is too slow, the thickness of a combustion zone is widened, the sintering rate is reduced, if the particle size is too fine, the combustion rate is too fast, the high-temperature retention time is short, and the yield and the quality of the sintered ore are reduced.
The granularity of the fuel which is generally transported into a sintering plant is 0-40 mm, the sintering production has strict requirements on the granularity of the fuel, the content of 0-3 mm is generally required to be more than 85%, and in order to meet the requirement, crushing treatment is required.
