Innovative Reuse of Electric Arc Furnace Slag as Filler for
The European steel industry produces about 70 million tons/year of steel by the electric arc furnace (EAF). The slag consists of about 15% by weight of the produced steel, thus from the perspective of the circular economy, it has a high potential as a co-product. This research aims to assess an innovative reuse of EAF slag as filler in Steel slag crushing process. Raw material (less than 350mm ) will be conveyed to vibrating feeder, grate of vibrating feeder is set to 100mm, material with size less than 100mm(from vibrating feeder) will be conveyed to cone crusher,Steel Slag Processing Gongyi Jingying Machinery
