摘      要：The development of heat recovery methods for dry granulation processes from blast furnace slag in the iron and steel industry is limited because of the high consumption of granulation energy during these *** determine the factors that influence the diameter of granulated particles,a paraffin test platform for gas quenching granulation was *** influences of air velocity,air flow rate,liquid mass flow rate,and liquid pipe diameter on the final particle size and mass distribution were *** results showed that the final particle size decreased(from 1.07 mm to 0.81 mm) with increasing air velocity(from 28.3 m/s to 113.2 m/s).However,when air velocity was higher than 60 m/s,its influence on particle diameter decreased *** experimental data were analyzed using SPSS Statistics software,which indicated that the effect of air velocity on particle diameter was the most significant,followed by those of air flow and liquid pipe *** effect of liquid mass flow was the least significant.
