Don't slag this off: steelmaking goes green CSIROscope

Mar 19, 2015· The fiery heart of Dry Slag Granulation. The molten slag is spun out into droplets and cooled to be used in cement manufacture. You may have heard it in the playground, but today we're bringing you the word 'slag' in another form altogether: one that's good for .

Wet Granulation Advantages And Disadvantages Biology Essay

Wet granulation and direct compression are the most important, with dry granulation (also termed as precompression or slugging) used in some circumstances. Fig shows the processes of wet granulation and direct compression broken down into their constituent stages.

blast furnace slag granulation process

Groundgranulated blastfurnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.

The granulation of the slag melt

Applications: granulation of the slag melt, mostly melt casting powder for continuous casting of steel. The inventive method of granulation of the slag melt includes a dispersion make of melt jet of high speed air flow, applying a layer of powdered material dispersed particles passing the dispersed particles through the bulk layer of powdery material, cooling and crystallization of the obtained granules.

Dry Granulation of Molten Slag using a Rotating Multi ...

Blast furnace slag is the main byproduct in the ironmaking process, which contains large amounts of sensible heat. In addition, it's the major raw material for cement. However, the sensible heat is wasted not only without any recovery in the traditional water granulation process at this present.

energy innovation austria, Issue 1/2018

slag can be put to work to produce process stream or generate electricity or for various other heating or preheating purposes. Saving resources With the newly developed dry slag granulation process water con sumption can be cut by up to 95 %. In addition, no energy is needed to dry the slag sand. With wet granulation subsequent drying con

A typical RecoDust process will often require temperatures from °C with a dry, pourable, and welldefined grain sized raw material input of approximately 300 kg/h. In one experiment, 94% of chlorine, 93% of fluorine and 92% of lead was eliminated from the steel mill dust with a 97% recovery of zinc.

Granulation | TENOVA

Tenova Pyromet has vast experience in the design and construction of wet granulation plants. The wet slag granulation process involves pumping water into the slag cold runner via a blower box to quench the molten slag. The inhouse designs have been proven in numerous applications and have shown to be both robust and reliable.

slag granulation plant process

Today rapid cooling of liquid slag in a closed water slag granulation plant is state of the art process The rapid cooling of the liquid BF slag in the water prevents the crystallization of slag and breaks the slag into small particles by thermal stress The liquid BF slag freezes in an amorphous granulate, called granulated BF slag The non crystallization rate of the water granulated BF slag .

Dry Granulation to Provide a Sustainable Option for Slag ...

Dry slag granulation is destined to replace conventional water granulation of molten slags in the not too distant future, creating a paradigm shift in the history of slag treatment. In this dry process, molten slag is atomised under centrifugal forces on a spinning disc and the slag droplets generated are quenched and solidified quickly using air.
