Description

Technical Field

[0001] The utility model relates to the field of fuel screening, in particular to an unpowered vibrating screen for sintered fuel. Background Art

[0002] Sintering fuel is required during the sintering process. The raw materials used for sintering mainly include iron ore powder, fuel, flux, and additives. The sintering process involves mixing the iron ore powder, flux, and fuel and heating them to cause a series of physical and chemical changes, ultimately producing a product with certain strength and metallurgical properties. The fuel used in sintering needs to be screened before entering the four-roller crusher, where it is crushed into fuel particles smaller than 3mm. Since the four-roller crusher accepts incoming material with a particle size of 10mm or less, and the raw material particle size of 10mm or larger accounts for 5%-10%, the raw material needs to be screened before entering the four-roller crusher to remove the particles larger than 10mm. Due to space constraints, it is impossible to install large-scale screening equipment in the fuel transmission line. Therefore, a small screening device that can fit the existing site space is needed to achieve the required fuel screening requirements. To achieve this, a vibrating screen is necessary to improve screening efficiency. In addition, existing vibrating screens are difficult to disassemble and replace. Therefore, a vibrating screen that is easy to disassemble and replace components and improves maintenance convenience is urgently needed. Utility Model Content
