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 …

Slag Crusher offered is used for crushing stag that is produced during smelting process through different processed applied in production. Slag in metals is present as form of undesired impurities at time of smelting which float to top in form of protective crust of oxides on top of metal being smelted, thus protecting liquid metal under it.

Dewatering Process The granulated slag and water mix is distributed evenly over the whole length of the drum. Axial vanes inside the drum continuously lift the slag sand onto a conveyor belt for immediate evacuation. The fine mesh on the exterior of the drum retains the slag sand and allows the water to filter through. The slag
