Granulated Slags

We are engaged in offering the 100% compliant Granulated Blast Furnace Slag (GBFS) to the global market. We end up with the best grade slag during the steel-making process. The slag, we offer, does not contain any metallic item, but consist of glass containing silicates and alumino silicates of lime.  

Features :

  • Is extracted from steel-making process and is quenched to form granules
  • Is the by-product obtained in the manufacture of pig iron in blast furnaces at around 1400oC to 1500oC in the molten form
  • Is obtained by rapidly chilling the molten ash from the furnace by means of chilled water and is grounded about 400 m2/kg of fineness by using state-of-the-art grinding mill to make GGBS.
