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.
Dry Slag Granulation – The Future Way to Granulate Blast Furnace Slag Fleischanderl A.1, Fenzl T. 2, Neuhold R. 3 1Primetals Technologies Austria Turmstrasse 44, .
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.
Metallurgical slags are produced at a massive rate of over 750 Mt/year, and carry a thermal energy equivalent to 40 Mt/year of coal. The potential mineral and thermal energy values of slags are in the order of $22 b and $3–6 b per year. Such attractive figures, together with tightening legislation on disposal of slag and the carbon footprint associated with the loss of mineral and energy ...
Dry slag granulation with heat recovery. Primetals Technologies, voestalpine Stahl, the FEhS – Building Materials Institute and the University of Leoben joined forces in an R&D program to develop a new dry-granulation technology using air to cool molten slag and recover the lost heat energy.
Jun 01, 2016· A prototype dry slag granulation system was proposed and designed in commercial scale. • The input and output flows of each slag-treatment system were identified. • Life cycle assessment on the dry slag granulation method and water quenching methods was carried out. • Economic costs and returns during the lifetime of slag were calculated.
RASA SYSTEM. The hot mixture of solid slag particles and water produced by contacting water with the molten slag released from a blast furnace is introduced into a tank equipped with an overow and a lter at the overow which permits a portion of the water and a minor fraction of slag nes to overow. The major fraction of larger slag particles collects at the bottom of the tank and is pumped as a ...

Dry granulation of blast furnace slag was experimented with in the Commonwealth Scientific and Industrial Research Organization (CSIRO), Australia. In this process, molten slag is atomized under centrifugal forces on a spinning disc and the slag droplets generated are quenched and solidified quickly using air ( Xie & Jahanshahi, 2008; Xie et al ...
Slag Granulation System "RASA SYSTEM" If molten slag, a byproduct produced when steel is manufactured in a blast furnace, is rapidly cooled with jet water, granulated slag is produced. Granulated slag is recycled as raw materials for cement, etc.
The system is automated to rapidly test circuits (~1 minute tests) and store historical data. Hatch's soft sensor uses installed flowmeters in tandem with statistical methods to calculated deviations in differential flow. Both leak detection methods result in much faster and more predictable leak detection. Dry Slag Granulation

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 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. This proven granulation process ensures economic ...
we developed the world's first closed-system slag granulation plant in 1967, Rasa has been a trailblazer in environmental engineering. In 2012, having acquired the chemicals business, Rasa Group launched a new initiative to bring greater value to the market, with "materials" as a key word. Expertise and Reliability Attested
