Blast Furnace Slag Granulation / Ironmaking / Our ...
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 2-friendly substitute of clinker in cement production) rather than a difficult and costly waste material.Paul Wurth has developed the INBA ® slag granulation process, incorporating our proprietary dynamic INBA dewatering drum.
Slag Granulation with Continuous Dewatering Ironmaking
Slag Granulation with the INBA Dewatering System Molten slag is often considered as a waste material when it is cast into slag pits. INBA slag granulation and dewatering system is the proven route for converting molten slag into a value added product for the cement industry. The INBA system comprises two main components

In the granulation section, the liquid slag is ‘quenched’ by pouring onto it an excess water stream. The evaporated water will be condensed in a condensing tower located above the granulation tank. This proven granulation process ensures economic granulation and produces valuable and consistent properties in the blast furnace slag.

Dry Granulation of Blast Furnace Slag - Steel360 …
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. Heat is recovered from the slag in the following ways. As the spray of slag particles moves outwards from the atomizer, heat is lost by radiation to the vessel and by convection to the air moving through the vessel.

Ground granulated blast-furnace slag - Wikipedia
Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.Ground-granulated blast furnace slag is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing ...

6-4-2020 · Dry Slag Granulation Water granulation is the most commonly used method to handle blast furnace slag and requires a granulation and a dewatering step to process the slag. In water granulation, the energy in the slag is lost from water evaporation and cooling and is difficult or impossible to recover.

Granulation - Wikipedia
Granulation is the process of forming grains or granules from a powdery or solid substance, producing a granular material.It is applied in several technological processes in the stone and pharmaceutical industries. Typically, granulation involves agglomeration of fine particles into larger granules, typically of size range between 0.2 and 4.0 mm depending on their subsequent use.

31-5-2019 · As a “wet” process, water granulation cannot recover high-grade waste heat from molten slags. The process consumes a large amount of water (about 1 ton of water per ton of slag is lost through evaporation) and may emit acid mist, H 2 S, and SO 2, causing serious air pollution.
AISTech2018 Dry Slag Granulation – The Future Way to ...
The wet granulation process operates with a high water to slag ratio of about 8:1. The advantage of the wet process is that it is accepting wide fluctuations in the mass flow and physical/chemical properties of the slag. However, the wet process faces also significant disadvantages:
