FIELD: metallurgy.
SUBSTANCE: raw materials for fabrication of palletised compound are compounded and grinded at the grinder of wet milling. As its fundamental slag-forming ingredient it is introduced blast-furnace slag, which mainly consists of calcium and silicon oxides numbering 55 - 75% of dry ingredients total mass. Additionally liquid sodium glass is introduced into aqueous suspension numbering 5 - 45% of aqueous suspension from compounding ingredient total volume weight. Pelletisation is implemented by means of suspension dispersion in a drying chamber at temperature 150 - 400°C in combustion materials of natural gas and air compound medium at ratio 1:(1.1 - 1.5).
EFFECT: abatement of the content of moisture and powdered fraction in finished compound and improving of palletised compound and granule strength.
