The Experimental Study of Molten Blast Slag Dry Granulation

Abstract:

Based on the comprehensive experimental test-bed of blast furnace slag waste heat recovery, we study the impacts which are caused by the changes of the key parameters, such as blast furnace slag discharged temperature, the speed of the granulation device, on the particle diameter distribution and sphericity, so as to master the best operating parameters of the blast furnace slag dry granulation, and provide experimental basic materials for blast furnace slag waste heat recovery. The results show that: when the discharged temperature of the blast furnace slag is controlled in 1400°C～1450°C, and the speed of the granulation device is controlled above 2000r/min, the sphericity is better, and 80% of the particle’s diameter will be 2～5mm.
