Dry granulation of titania slag was carried out at the 500 kW DC furnace on site. In this instance compressed air was used as granulation medium. Two rectangular guide plates placed on the slag taphole side of the furnace channelled granulated particles produced during the granulation trials.
A dry granulation experiment was done by means of a rotary cup atomizer for blast furnace slag instead of the currently used water quenching process because it is unable to efficiently recover the ...
At the present molten slag from a blast furnace () is granulated by impinging much water without any recovery of its much sensible heat (1823K), polluting water and atmosphere. To solve these problems, we studied the dry granulation of molten slag by Rotary Cup Atomizer (RCA), in .
Dry granulation is traditionally referred to as extrusion granulation. And you don''t need to add water or adhesives to the fertilizer process. In the extrusion granulation process, the raw material is gathered into the primary powder in the fertilizer granulator under high pressure, and the powder is extruded into fertilizer granules between ...

Dry Granulation of Blast Furnace Slag for Heat Recovery Blast furnace slag is known as a byproduct from the production of hot metal at integrated steel and iron mills. Approximately 300 kg of this liquid slag with a temperature of about 1500°C is tapped together with each ton hot metal.
Slag handling is an important aspect of modern blast furnace operation. Today, blast furnace slag is a saleable product (granulated slag sand used as CO 2friendly substitute of clinker in cement production) rather than a difficult and costly waste Wurth has developed the INBA ® slag granulation process, incorporating our proprietary dynamic INBA dewatering drum.
Dry slag granulation with heat recovery Primetals Technologies, voestalpine Stahl, the FEhS – Building Materials Institute and the University of Leoben joined forces in an RD program to develop a new drygranulation technology using air to cool molten slag and recover the lost heat energy.
Granulation is the process of forming grains or granules from a powdery or solid substance, producing a granular is applied in several technological processes in the chemical and pharmaceutical industries. Typically, granulation involves agglomeration of fine particles into larger granules, typically of size range between and mm depending on their subsequent use.
Dry granulation of liquid BF slag is being developed in many countries along with heat recovery process. The dry granulation process of liquid slagis described below. Dry slag granulation process is essentially to atomize the liquid slag and then to cool the particles rapidly so as to produce a glassy slag.
A method of controlling a supply of coolant gas to a dry slag granulation system, the system comprising: a rotary atomising granulator; a slag receptacle, for supporting a slag bed which is formed thereon when slag particles are expelled from the granulator, the slag receptacle comprising a plurality of cooling inlets for cooling respective zones of the slag bed; and at least one height ...
Dry Granulation Concept. Dry slag granulation is based on molten slag atomisation using a variable speed rotating cup or dish (see Figure 1). The slag is delivered on to the centre of the cup from a slag runner via a vertical refractory lined pipe. The rotation of the cup forces the slag outwards to the cup lip where it is atomised (see Figure 2).
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.
A slag granulation device comprises a slag granulation chamber; a rotary atomising granulator (5, 6) to atomise molten slag, the granulator being mounted in the granulation chamber; and an air supply (33) to supply air to the molten slag (9) before the slag is atomised. The system further comprises a slag delivery mechanism for delivering slag to the granulation chamber.
Heat recovery during slag granulation provides energy recovery of 20 MWth or 6 MWel regarded to a slag mass flow of 1 t/min. springer. Siemens VAI wants to build a pilot plant for dry slag granulation for testing the possibility of integrated heat recovery, needing small amounts of liquid slag .

Abstract. Slag dumping and water granulation are the most commonly used slag treatment methods in the metallurgical industries. In both processes, water is present (by desire for cooling and dispersion or as a result of rain accumulation) and thus equipment and operations are designed to minimize and mitigate the risk of steam explosions resulting from the inappropriate contact of slag with water.
Dry Slag Granulation Significant research and development has occurred in the area of Dry Slag Granulation (DSG) over the past decades. Development of DSG technologies is driven by the desire to improve safety and sustainability of conventional slag handling methods. The most significant advantage of DSG is that it provides a safer and more
