May 31, 2019· The next work by Cooksey et al. provides an overview of the design and operation of a dry slag granulation pilot plant at CSIRO. This overview covers some of the RD activities and findings on the design of rotating disk for atomization of melts, cyclonic fluidized granules, heat transfer, and recovery.

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 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.
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. Dry Granulation of Blast Furnace Slag steel360
Paul Wurth's dry slag granulation process with energy recovery has won the ... After a series of trials, an industrial pilot plant began construction in ... which can also been applied to steelmaking, EAF or ferronickel slags".
Dry slag granulation; Services. Construction of complete hot blast cupola plants Modernization of existing cold and hot blast systems, so that current emission limits are met Performance increase through oxygen use, conversion of furnace and gas handling system ...
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.
5th International Congress on the Science and Technology of Steelmaking 2012, Dresden, Oct. 13 ICS 2012 Current status and future direction of CSIRO's dry slag granulation process with waste heat recovery Sharif Jahanshahi and Dongsheng Xie CSIRO, Box 312, Clayton South, VIC 3168, Australia Corresponding author: email [email protected] Abstract Dry slag granulation (DSG) could make a ...
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.
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.

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.
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 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.
Mar 16, 2015· The process, known as Dry Slag Granulation, also reduces water use and greenhouse gas emissions, and is the focus of an agreement signed by CSIRO and the .
China creates about sixtenths of the blast furnace slag in the world, and adoption could have a major impact, says Cooksey. "History shows that it takes a decade or two to go from an idea to a commercial product in the metal production industry; on dry slag granulation, we're much closer to the end of it than we are to the start," he says.
A new dry granulation process for molten slag is described. The process produces a slag product of high glass content, suitable for cement manufacture, and allows heat recovery from the slag. Experimental tests have been carried out on a laboratoryscale plant to prove the new process.
total process, from entering into the granulation unit and exiting the dewatering section, has so far only taken 30 seconds. For ferroalloys, the demand for a dry endproduct requires to dry the material, typically using a rotary dryer. The typical granule has a deformed .
Experimental results on the dry slag granulator pilot plant have demonstrated that the process can effectively produce glassy slag granules from molten iron blast furnace slag, and recover ...
"Development of Dry Slag granulation technology and energy recovery system for blast furnace slag for proving clinker compatible product " in the Department of Chemical Engineering. Other things being equal, preference will be given to SC/ST candidates. Duration: Initially .
