  High-temperature modification and air-quenching granulation of steel slag

  202185 · The maximum crushing value of slags with different grain sizes is considered as the crushing value of this type of air-quenched granulated steel slag. It can be seen from Table 3 that, with the increase in the proportion of modifier, the crushing value of air-quenched granulated steel slag increases gradually while the compactness decreases.

  Recovery of metal from slag/mixed metal generated in …

  200516 · The studies showed that in the case of the charge chrome plant, crushing of mixed metal and slag to below 10 mm followed by jigging of the −10+1 mm material and tabling of the −1 mm material would help recover 10 tpd of metal from the 18 tpd of mixed metal. Based on the studies, a plant is now operational at the Ferro-Alloy Plant (FAP ...

  Investigation on cold bonded pelletization of iron ore fines …

  199211 · The strength development characteristics of pellets containing slag-clinker is similar to those containing clinker as the binder. Around 50% of the ordinary portland cement required for making pellets of desired properties can be stubstituted by slag. The crushing strength of the pellets is found to increase with increase of diameter of the pellets. The …

  Comparison of properties of steel slag and crushed limestone aggregate ...

  200331 · The steel slag aggregate, presently produced by a steel plant in Saudi Arabia is utilized in asphalt concrete. The steel slag is produced during the direct reduction of iron in an electric arc furnace. It disintegrates to smaller size fractions, due to rapid cooling, thereby necessitating minimal crushing to produce aggregates of the desired size.
