Steel slag can also act as a corrective raw material for iron in the cement production process due to the high content of iron oxides. However, steel slags have the disadvantage of poor grinding performance . Grinding steel slag particles into fine powder will cause additional grinding energy consumption and increase the mill fault ratio.

ball mill using (i) three loads of single size media, i.e., 40, 25.4, and 12.7 mm and (ii) a mixed load of balls with varying sizes. In order to simulate the industrial ball milling operation, the feed to the mill consisted of slag with natural size distribution less than 850 m. Grinding kinetic modeling and

HLM Vertical Grinding Mill for Steel Slag Processing Line . The application of steel slag. Steel slag is composed of various oxides formed by the oxidation of silicon, manganese, phosphorus, sulfur and other impurities in pig iron during the smelting process and salts formed by the reaction of these oxides with the solvent.

Flowsheet. This dry process developed by Loesche for recovering metals from steel slag combines all the advantages of conventional processes: Efficient and cost-effective metal recovery in the coarse range. Virtually metal recovery down to the finest fractions range by means of optimised dry grinding, classification and sorting technology.

Slag is defined a type of sand that is traditionally derived from steel. It is a rough, stony-like waste product that is created during smelting or in this case from deburring. After a grinder deburrs sheet metal, the parts that chip off are known as slag. Slag grinding removes all heavy slag quickly and effectively, using rotating brushes that ...

Steel slag grinding is an important link in the steel slag treatment and comprehensive utilization process. It is generally believed that steel slag has a glass body structure, high iron content, and high product fineness requirements, making it difficult to grind using vertical mills. However, ball mill grinding steel slag requires pre-drying …
