Description

Technical Field

[0001] The utility model relates to the technical field of fuel crushing and screening, in particular to a fuel crushing and screening device. Background Art

[0002] Sintering is a traditional process that converts powdered materials into dense bodies. People have long used this process to produce ceramics, powder metallurgy, refractory materials, ultra-high temperature materials, etc. Generally speaking, after the powder is formed, the dense body obtained by sintering is a polycrystalline material, and its microstructure is composed of crystals, glass and pores. The sintering process directly affects the grain size, pore size and grain boundary shape and distribution in the microstructure, which in turn affects the performance of the material.

[0003] The fuel used in sintering requires that the -3mm part accounts for more than 75%, while the -3mm part of the original fuel particle size accounts for 40%-50%. At present, the fuel is crushed by belt transportation and directly enters the four-roll crusher for crushing. After crushing, it is directly put into the warehouse for use. This not only increases the workload of the four-roll crusher and shortens the roller skin replacement cycle, but also causes the four-roller material flow to be large and the particle size does not meet the standard. At present, the -3mm part of the fuel after crushing is about 70%, which does not meet the use requirements, resulting in high sintering solid fuel consumption, fuel segregation, and poor strength of the sintered ore on the upper layer of the trolley. Therefore, a fuel screening device is needed to realize fuel screening, reduce the workload of the four-roll crusher, and extend the use cycle. Utility Model Content
