Abstract:
For the purpose of high quality and low production cost of cement-bonded cold pellets, the effect of CaO addition on the Physical and Chemical properties was examined experimentally.
Pellet was added with a large addition of cement /Cao mixing ratio (4-8 mass %) and lime (0-6 mass %). During the steam curing process, a half amount of CaO added changed into some calcium compound such as Ca(OH)2 and CaCO3.
The reducibility Using H2 and Mixing gas (80.8%H2, 14.2% CO, 5% CO2) is higher in pellets with CaO added compared to those with no CaO addition. However, poor crushing strength values were found in pellet with CaO addition compared to those without CaO after drying at 600°C and 900°C.
