Beschreibung
Zusammenfassung:	A method of production of cement bonded agglomerated ore not depending on yard curing which can improve the environment, save labor, and improve yield is provided, that is, a method of production of cement bonded agglomerated ore which adds Portland cement as a binder to dust produced from an iron works and/or fine powder ore, treats the same by mixing, moisture adjustment, and kneading steps, then pelletizes it by a pan pelletizer and suitably thereafter cures it to produce blast furnace-use cold pellets or sintering-use minipellets having the required crushing strength, which method charges the raw pellets from the top of a vertical type container and discharges them from the bottom end to form a moving bed and cures the raw pellets in the period from charging to discharging.
