The technology of slag processing through granulation starts by effusion of slag from the Blast Furnace. The melted (liquid) slag at the temperature of 1300°C – 1550°C is led into the granulation chamber through a channel system (with an internal refractory lining). · 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.
