Dry Granulation of Blast Furnace Slag

Apr 04, 2019 · 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. Atomization is done using a rotary cup air blast atomizer (Fig 1).

Some Fundamental Aspects of Dry Slag Granulation Process

Abstract: There is a growing interest in development of a dry slag granulation (DSG) process so as to recover the sensible and latent heats from molten slags and convert iron blast furnace slags into a glassy phase that is a suitable replacement for Portland cement.

Blast Furnace Slag Granulation / Ironmaking / Our ...

The process is highly flexible; and the compact sub-plant can be applied to any furnace configuration. Granulation, dewatering and storage of the slag can be done adjacent to the furnace or can be split up to suit available plant space or logistics.

Blast furnace slag granulation at cast house – IspatGuru

May 05, 2013 · The process of slag granulation involves pouring the molten slag through a high pressure water spray in a granulation head, located in close proximity to the blast furnace. Granulation process is the controlled quenching of the slag in cold water which does not give time for crystalline growth to take place.

Dry slag granulation: producing valuable by-products from ...

Nov 06, 2019 · However, water granulation consumes large volumes of water and may generate acid mist causing air pollution. More importantly, the wet process does not recover the large amount of high-grade heat contained in molten slag. On cooling from around 1500 °C to ambient temperature, one tonne of molten slag releases about 1.8 gigajoules (GJ) of heat.

Granulation of titania slag - SAIMM

This is shown by the photograph in Figure 2. The slag stream is fragmented by the water stream into small particles that are suspended in the granulation tank. From there the slag-water slurry is pumped into the slurry or dewatering tank. All excess water is drained and the wet slag …

Ground granulated blast-furnace slag - Wikipedia

To cool and fragment the slag a granulation process can be applied in which molten slag is subjected to jet streams of water or air under pressure. Alternatively, in the pelletization process the liquid slag is partially cooled with water and subsequently projected into the air by a rotating drum.

Granulation - Wikipedia

The granulation process combines one or more powder particles and forms a granule that will allow tableting to be within required limits. It is the process of collecting particles together by creating bonds between them. Bonds are formed by compression or by using a binding agent.

WO2016020253A1 - Slag granulation system - Google Patents

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 ...

The SLAG-REC project for an innovative direct dry ...

Contrary to the constancy of the production process in blast furnaces, in EAFs slag production is discontinuous (slag is being eliminated from steel periodically, and its temperature and fluidity vary from heat to heat), thus for EAFs it is impossible to use of the wet granulation systems …

The granulation of the slag melt -

The granulation of the slag melt, mainly casting powder for continuous casting of steel, comprising a dispersion make of melt jet of high speed air flow, drawing on dispersed particles of the layer of powder material, cooling and crystallization of the obtained granules, wherein applying a layer of powdered material dispersed particles of the ...

(PDF) A Review of Granulation Process for Blast Furnace Slag

Blast furnace slag is the main byproduct in the ironmaking process, which contains large amounts of sensible heat. In addition, its 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.

Dry Slag Granulation (DSG) - YouTube

May 09, 2019 · Primetals Technologies has developed a new innovative blast furnace dry slag granulation process with heat recovery at the voestalpine pilot plant in Linz, Austria.
