Design and Operation of Dry Slag Granulation Pilot Plant ...
12%The concept of dry granulation is that molten slag is atomized under centrifugal forces on a spinning disc, and the liquid droplets generated are rapidly quenched and solidified using air to produce solid slag granules suitable for use as a SCM, as per water granulation. The hot air can be recovered and used in other process operations.

Dry Slag Granulation: A Path to Improving the Safety and ...
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 …

Welcome to Evotech
The process of cast house slag granulation starts with separation of molten slag from liquid hot metal. The molten liquid slag is led into the granulation chamber through a series of runners protected by lining and sand. Direct contact between pressurized water stream and molten liquid slag takes place in the granulation chamber.

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. Atomization is done using a rotary cup air blast atomizer (Fig 1). The particles cool as they travel through the air and are then cooled further in a fluidized bed. Both of these cooling processes provide ...
