04-04-2019· 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 ...
Dry slag granulation is based on molten slag atomization using a variable speed rotating cup or dish (see Fig. 1). The slag is fed from the slag runner via a vertical refractory lined pipe directly onto the center of the rotating cup.

23-08-2016· The energy in slag is lost through dumping and water granulation processes, and where slag is sold as a by-product, it is for its chemical content only. Here, dry granulation processes also offer advantages including the production of by-products which hold value in both their chemical content and physical properties and heat recovery.
