Vipeak VSI5X impact crusher realize blast furnace slag waste to treasure

Blast furnace slag is the residue after processing blast furnace slag , which has been plagued by the problem of handling social problems. Blast furnace slag is a molten silicate material discharged from the smelting of pig iron blast furnace . When the blast furnace , the furnace when the temperature reaches 1400 ~ 1500 ?, the material will become molten liquid in the liquid phase floating on the water of iron slag , iron by iron through the main trench mouth skimmer separation or slag discharge port this is blast furnace slag . Blast furnace slag from the gangue , ash, flux and other contaminants can not enter the pig iron composition is a eutectic mixture .
Blast furnace slag is handled mainly in the following three ways: First, the temperature cooled slag becomes hard, dry residue ; Second, the high-temperature liquid water quenching crushed slag , slag becomes loose ; Third, the use of steam or compressed the high temperature liquid slag air strike scattered slag becomes fluffy cotton . Among them, the utilization of blast furnace slag is a better option . However , blast furnace slag reprocessing issue has been unresolved .
