Dry slag granulation: producing valuable by-products from waste
Molten slag is atomised under centrifugal forces exerted by a spinning disc to produce droplets which are then quenched and solidified using air to recover the heat. This method produces glassy slag for cement production and simultaneously recovers waste heat as hot air, which can be used onsite for drying, preheating or steam generation.
