Slag Production And Grinding 2

Granulated Blast Furnace Slag (GBFS) contains a high level of moisture, it is hard to grind and very abrasive. 2 Natural pozzolans may not be as hard to grind as GBFS but may contain high moisture levels and be abrasive. 2 Both of these materials require grinding systems designed to deal with high moisture, hardness and abrasiveness. GBFS can be utilized in the cement making process as an

Steel Slag - an overview | ScienceDirect Topics

Depending on the used production technology, the steel slag can be divided into a basic oxygen steel slag, an electric arc furnace slag and a ladle furnace slag (De Brito and Saika, 2013). The steel slag is used as a secondary cementitious binder, or aggregates for road construction ( Sheen et al., 2013 ; Manso et al., 2004 )

Study of intergrinding and separate grinding of blast

The slag was activated mechanically by grinding the slag to 250, 360 and 420m2/kg Blaine surface area, thermally by curing mortar specimens at 20 , 40 and 60 C, and chemically by mixing the

Efficient and reliable handling of GBFS and ... - Global Slag

Mar 03, 2008 Grinding slag for cement replacement requires only about 25% of the energy needed to manufacture normal Portland cement. Without the use of granulated material the total volume of slag produced could not be viably or economically utilised in other processes, such as aggregate for example, and would inevitably go to landfill as in the past
