Theory and Practice of Sintering of Iron ore – IspatGuru

25-11-2018  Theory and Practice of Sintering of Iron ore. Sintering of iron ore is a generic term which is used to describe the process whereby a sinter mix (raw mix or green mix) of iron ore fines, fluxes, fuel (coke breeze) and plant return fines (e.g. mill scale, blast furnace dust, and returned sinter fines etc.) are converted into a particular form of agglomerate.

time ago to nrixiiig iron ores in sintering plants. The mixing disc has the advantage that it requires relatively small space and that the mixing process can he observed quite well. But cu the other hand it has the great disadvantage that the retention time of the nt.cterial to be mixed on the disc is limited, ar:d that is why its use must lie restricted to ores recliiiring only, it short miring time.

Sinter plant - Wikipedia

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace. The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical properties of the ingredients. The purpose of sinter are to be used converting iron into steel.
