Basic slag is a co-product of steelmaking, and is typically produced either through the blast furnace - oxygen converter route or the electric arc furnace - ladle furnace route. To flux the silica produced during steelmaking, limestone and/or dolomite are added, as well as other types of slag conditioners such as calcium aluminate or fluorspar .
The grinding plant for Anshan was designed for a grinding capacity of 90tph at a ground blast furnace slag product fineness of 4000cm 2 /g according to Blaine. However, following the market trend, the plant now produces 83tph of ground blast furnace slag with a fineness of 4300cm 2 /g (acc. to Blaine).

Coke is the ideal blast-furnace fuel because it is strong and hard enough to resist the crushing and grinding effects of the furnace burden, and its porosity allows the ready passage of gas upward through the charge, and rapid combustion before the tuyeres.
Grinding of blast furnace slag is conventionally performed in a tube mill with a dryer, which is a power-intensive option. Energy efficiency of this process can be improved by grinding the blast furnca slag using vertical roller mills (VRM) or by using a VRM as a pre-grinding step for the tube mills.
A preliminary reduction of the dried granulated slag may be made in a ball mill, and the final grinding, after the requisite amount of slake lime has been added, made in a Fuller-Lehigh mill, tube mill, or other suitable fine dry grinder.
