Ground Granulated Blast Furnace Slag/Granulated Blast Furnace Slag

Product Details

Ground granulated blast furnace slag (GGBS) is a by-product from the blast-furnaces used to make iron. Blast furnaces are fed with controlled mixture of iron-ore, coke and limestone, and operated at a temperature of about 1,500°C. When iron-ore, coke and limestone melt in the blast furnace, two products are produced—molten iron, and molten slag. The molten slag is lighter and floats on the top of the molten iron. The molten slag comprises mostly silicates and alumina from the original iron ore, combined with some oxides from the limestone. The process of granulating the slag involves cooling of molten slag through high-pressure water jets. This rapidly quenches the slag and forms granular particles generally not bigger than 5 mm. The rapid cooling prevents the formation of larger crystals, and the resulting granular material comprises around 95% non-crystalline calcium-alumino silicates. The granulated slag is further processed by drying and then grinding in a vertical roller mill/rotating ball mill to a very fine powder, which is GGBS.
