“…The influence of diameter of drum mixer on granulation has been studied, but it is still unclear. Suzuki 8) reported that larger drum mixer and pan pelletizer showed an advantage for granulation because the rolling length of the particle became longer. However, Oyama 9) and Yakashiro 10) reported that larger drum mixer showed a disadvantage because the granulated particles are easy to collapse in the larger drum mixer.…”

Recently, an increase in the amount of fine ore, such as Marra Mamba or Brazilian concentrated ultra fine, in raw material of sinter ore lowers the permeability of sintering bed and the yield of the sinter ore. The collapse of voids in the sintering bed will cause these problems although the bed has a porous structure. Therefore, controlling the bed structure by including loosely packed regions and densely packed regions in the same packed bed has been discussed. This new idea is named MEBIOS (Mosaic Embedding Iron Ore Sintering). In this report, permeability improvement techniques based on MEBIOS concept were studied. In order to granulate large dense green balls with ordinary sinter feed ore, mathematical simulation and granulation tests by using pan pelletizers were carried out. The influence of rim height and pan diameter on movement of raw material in pan was investigated. Also, influence of rim height and slope angle on hold-up and influence of residence time on diameter of green balls were studied. Finally, this technique was installed in Wakayama No. 5 sinter plant. As a result, yearly average productivity of 1.41 t/m 2 /h and the use of 135 kg/t-sinter Brazilian concentrated ultra fine ore were achieved with 1 350 MJ/t-sinter heat consumption for sintering in 2011.

“…(11) Joko et al 16) reported that observed residence times were comparable to theoretical values suggested by Saeman. On the other hand, Suzuki et al 15) reported that the axial transport velocity suggested by Saeman needs to be compensated by a correction factor (1.8 times) because of accelerating particles in the drum mixer. That is to say, the observed residence time was shorter than the theoretical values suggested by Saeman.…”

“…14,21) For this concept to be accepted, when the drum diameter is made to be the D times, the new Vz becomes the drum diameter to the power of 0.5 multiplied by the original Vz from Eqs. (11) and (15). On the other hand, when the drum diameter is made to be the D times, the new occupation of cross-section in the drum becomes the drum diameter to the power of 2.0 multiplied by the original drum diameter.…”

“…In contrast there are few reports on the raw material behavior for a drum axial direction and residence time in a continuous type drum mixer. [14][15][16][17][18] Saeman 19) reported on the residence time of the raw material in the continuous type drum mixer for the rotary kiln. Suzuki et al, 15) Joko et al, 16) and Takasaki et al 17) compared the observed residence times to the theory predicted by Saeman.…”

This research study investigates the factors associated with pelletisation in the production of fly-ash aggregates and its performance in concrete. To investigate this influence, experiments were carried out in different stages to explore the effect of factors responsible for pelletisation, which were designed through Taguchi's experimental design. Additionally, the influence of each parameter on the engineering properties of the produced aggregates was determined using Grey relational analysis. Further, considering the optimised pelletisation factors of the laboratory-scale studies and with the help of an industrial-scale pelletiser, mass production of fly-ash aggregates was carried out and characterised for their engineering properties. The test results indicate that these aggregates are mainly governed by water content followed by the angle and speed of pelletizing disc. It is observed from the results that the engineering properties of aggregates produced on an industrial scale are found to be better than sintered aggregates and also comparable with that of natural aggregates except for water absorption. The properties of concrete produced with fly-ash aggregates, light weight sintered aggregates and natural aggregates were also studied. The results showed that properties of concrete produced with fly-ash aggregates are in good correlation with those of conventional concrete produced with natural aggregates.
