Abstract Based on the granulation technology for high temperature molten blast furnace slag by rotary cup, visualization experiments were conducted by applying water as the substitute for slag and a rotary cup with diameter of 110mm to investigate the flow mechanism on the rotary cup surface and the formation of liquid ligament at the edge of the rotary cup. The dynamic behaviors of the liquid ligament length and the diameter of ligament head were obtained. The effects of rotary speed, liquid flow rate on diameter distribution of the granulated droplets were discussed. The experimental results indicate that the liquid film on the cup surface formed some heaves along the edge of the cup and formed liquid ligaments along the tangential direction of the rotary cup movement; the ligament length almost linearly increased as time progressed, while the diameter of ligament head approximately kept a constant value. The average diameter of the granulated droplets decreased with the increase of rotary speed and the decrease of the liquid flow rate.
