SiO2 and Al2O3 are two important minerals that can affect the mechanical and metallurgical properties of sinter. This investigation systematically studied the influences of these minerals and revealed their functional mechanisms on sinter quality. Results showed that with an increasing Al2O3 content in sinter, the sintering indexes presented an improvement before the content …
2020-7-20 · Sinter is a clinker-type iron bearing material that is produced when a mixture of iron ore fines known as sinter feed, finely ground fluxes, carbon (coke breeze or anthracite) and various recycled iron bearing materials are uniformly fired along a continuous traveling grate reactor. Fuel in the sinter mix is ignited and generates
Iron ore concentrate is produced from the magnetite iron ore in the beneficiation process and is used for the production of pellets for blast furnaces and sinter. The concentrates are non-toxic, non-flammable and non-explosive. The concentrate is shipped as a bulk commodity by rail using the open-top rolling stock and by sea. Manufacturer: SevGOK.
the sinter varies between 30–42 mm with the initial diameter of granules of 3.2 mm. Particles of raw mixture including iron ore, coke fine, limestone and et al. are pelletized into granules. Typically the mean diameter of iron ore particle is controlled at 3–5 mm. Coarser particle inclines to become the nuclei with
