Description
Technical Field

Background
Sintering is a process of mixing and granulating various iron-containing raw materials, fluxes (quicklime, limestone, dolomite, magnesite and the like), fuels (coke powder, coal dust) and the like, and paving the mixture on a sintering machine for ignition, air draft and sintering. The fuel is relatively low in the whole sintering batch, but plays a crucial role in the sintering process. The fuel particle size is an important index of interest in sintering production, and it is generally required that the proportion of <3mm in the sintered fuel particle size is 70% or more. If the fuel particle size is too thick, the burning rate is slow, the thickness of the burning zone is widened, and the sintering rate is reduced; the fuel granularity is too fine, the burning rate is too fast, the high-temperature holding time is short, the yield and quality of the sinter are reduced, and the too fine fuel can be pumped away in the sintering process, so that the fuel utilization rate is low and the fuel is wasted. In the fuel crushing, a roller crusher, a hammer crusher, a reaction crusher and the like are used as more crushers, and at present, crushed fuel has the phenomena of excessive crushing and more large-size-fraction fuel, so that the utilization rate of sintered fuel and the sintering production process are influenced.
