electric arc furnace slag recycling machinery

EAF slag recycling

EAF Slag is produced in an Electric Arc Furnace. The visual appearance of the slag is a dark greyish colour. With respect to other slags (blast furnace slag), it can be tougher, with a density of about 20 - 25% greater than basalt or BFS. When crushed, the pieces have a typical cubical shape.
