Abstract. ISO 4701:2017 specifies the methods to be employed for determination of size distributions by sieving of iron ore and direct reduced iron (excluding briquetted iron), utilizing sieves having aperture sizes of 36 µm or larger. The size distribution is expressed in terms of mass and percentage mass, passed or retained on selected sieves.

In general, the reduction of Fe 2 O 3, called hematite, does not occur directly to metallic iron, Fe.If the reduction temperature is lower than 570 °C, reduction to Fe occurs stepwise from Fe 2 O 3 to Fe 3 O 4, called magnetite, and continues to Fe.The intermediate oxide, wüstite Fe (1−x) O, is not stable at temperatures lower than 570 °C. At reduction …

The air jet sieve is a sieving machine for single sieving, i.e. for each sieving process only one sieve is used. The sieve itself is not moved during the process. The material on the sieve is moved by a rotating jet of air: A vacuum cleaner which is connected to the sieving machine generates a vacuum inside the sieving chamber

The sieve function can be realised via LIGGGHTS commands where each sieve opening and sieve spacing can be flexibly set (as shown in Fig. 4) To speed up the sieving process, the stack of sieves was then set vibrating horizontally for 2 min. After sieving process, the mass of the iron ore granules remaining on each sieve was obtained.
