| Abstract: | The effective factors of SiC premix powder spray prilling were analyzed through the experiments.The performance factors,such as inlet and outlet temperature,solid content of slurry,pressure,feedspeed play an important role to the spray prilling of SiC.The optimization of the spray process were performanced.The SiC powder with apparent bulk density of 0.91 g/cm3 fluidity of 20 s(the amount of sample is 30 g) was prepared. |
