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.

Products › Ironmaking and steelmaking › Slag Granulation

The slag granulation plant comprises three sections: for granulation, dewatering and storage. 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.

DRY SLAG GRANULATION WITH HEAT RECOVERY*

There are two methods in which slag can be fed to any slag granulation plant. The first involves a granulator which is located close to the furnace and enables the slag to be delivered to the plant direct from the slag runner. The second is a system 288 ISSN 2176-3135

Hatch Ironmaking Technologies Dry Slag Granulation

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.

Granulated Blast Furnace Slag an overview

Adding higher amounts of slag results in a higher sulphate resistance and lower heat of hydration properties. When producing such cement, slag is usually the hardest to grind, and it forms the coarsest portion, while the cement is ground the finest [9]. A potential problem is moisture, which occurs in blast furnace slag during the granulation

Slag recycling recovery

The increase in production volumes in 2019 was 10.8 % over the previous year, after an 11 % increase in 2018. The results show that slag cements are in vogue in the USA and that the demand cannot be met by the existing granulation plants alone. That is why around 2.3 Mta of ground granulated blast furnace slag was imported in 2019.
