Abstract
The present research reports the effect of binder addition on the physical and mechanical properties of green and fired mill scale pellets. A mixture of mill scale powder and varying weight percentage of bentonite (1, 1.5 and 2 wt.%) and molasses (2.5, 5 and 7.5 wt.%) binders were used separately to prepare green mill scale pellets by hand rolling to form spherical balls of diameter around 10 mm and then fired at 1,100 °C for 1 h. It was observed that the moisture content in pellets made with the addition of bentonite was found in the range of (6.16–6.70 wt.%) which was higher compared to those made with the addition of molasses (2.40–4.18 wt.%). A drop number in the range of (1.33–5.33) and (20.33–47.67) were observed for bentonite and molasses bonded pellets respectively. The compressive strength for bentonite bonded pellets varied from (633–780) N cm−2 and molasses bonded pellets it ranged from (179–213) N cm−2. X-ray diffraction study revealed the formation of only hematite phase after sintering at 1,100 °C.
