    Dry Granulation of Blast Furnace Slag - Steel360 News

    A rotary-cup, air-blast atomizer was built, with a cup of 100mm diameter and a speed range of 500-1500 rev/min. The slag flow rates used in the tests varied from 0.2-0.5 kg/sec. The tests were restricted to duration of around 2.5min because of the limited capacity (around 30 kg) of the laboratory slag melting furnace.
