Approximately 300 kg of this liquid slag with a temperature of about 1500 °C is tapped together with each ton hot metal. This means a worldwide annual production of about 400 million tons of blast furnace slag. Further processed, water granulated blast furnace slag can be produced, if the liquid slag is cooled down rapidly for solidification.

Process: vertical mill, ball mill process. Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. Ground granulated slag is often used in ...
The granulated slag is further processed by drying and then grinding in a vertical roller mill or rotating ball mill or roller press to a very fine powder which is called GGBS Comparison of GGBS vs FLY ASH GROUND GRANULATED BLAST FURNACE SLAG GGBS can be used as a partial replacement of OPC cement in concrete production at batching plants.
Grinding of cement clinker and granulated blast furnace slag in roller grinding mills (vertical airswept grinding mills) is a technology introduced by Loesche. The first use of a Loesche mill, with a grinding track diameter of only 1.1 metres, was used as long ago as 1935. However, the breakthrough in grinding this type of material on the vertical
After de-ironing the slag enter the vertical mill for grinding. Dried and grinded slag powder is collected by the separator and sent into the finished product silo by air chute and bucket elevator. The discharged slag is sent back to the mill by conveyor and elevator. The drying heat source is provided by an air heating furnace.
The terms blast furnace slag (BFS) and granulated blast furnace slag, as well as LD slag and electric furnace slag are used for finer distinctions. With high-quality iron ore grades with an iron content of 64 to 67 %, a blast furnace typically produces about 0.25 to 0.30 t …
