Steel Slag - an overview ScienceDirect Topics

Selective use and quantification of steel slag having suitable properties are important aspects for manufacture of SSBC. The slag should be magnetically reseparated prior to grinding for SSBC. Both too fine and too coarse particles are not suitable for SSBC. If particles are very fine, impurities such as dust might be incorporated; if they are too coarse, additional crushing will be necessary and, thus,

When piecewise regression analysis was applied to experimental data it was found that the particle size distribution of the slag products exhibits multifractal character. In addition, grinding of slag exhibits non-first-order behavior and the reduction rate of each size is time dependent. The grinding rate and consequently the grinding efficiency increases when the particle size increases, but drops sharply near zero after prolonged grinding

Slag - Wikipedia

Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore. Slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals. While slags are

Characteristics and applications of iron and steel slag ...

Just like air-cooled blast furnace slag, this slag has a hydraulic property and there is no risk of alkali-aggregate reaction. Because of the powerful latent hydraulic property that results from fine grinding, this slag is used in products such as Portland blast furnace slag cement. When blended with cement, the ground granulated blast furnace slag becomes Portland blast furnace slag cement with the same properties as ordinary (Portland) cement. The advantages of this blast furnace slag ...

Ground Granulated Blast Furnace Slag - an overview ...

Ground granulated blast-furnace slag, more commonly referred to as slag or slag cement, is a by-product of steel production. Slag is primarily composed of CaO, SiO 2, aluminum oxide (Al 2 O 3), and magnesium oxide (MgO). When used as part of a portland cement concrete, slag reacts with both the water (latent hydraulic reaction) and the hydrated cement paste (pozzolanic reaction), resulting in a

The blast furnace slag after granulation and grinding finds extensive use in cement and concrete. The steel slag, however, is yet to find a value added application except for its occasional usage as a cementitious binder. More often than not it is used as a landfill material. Most of the recent work therefore has been focused towards finding and exploiting the potential advantages of steel slag as a

Key properties of grinding media are size, density, hardness, and composition. Size: The smaller the media particles, the smaller the particle size of the final product. The grinding media particles should be substantially larger than the largest pieces of material to be ground. Density: The media should be denser than the material being ground.
