Abstract：To accurately control the spherical particle growth in rotary drum granulation,an on-line particle size inspection method based on the image analysis technology was proposed.Experimental platform of particle image recognition was built using industrial camera,and image analysis software was developed.The results show that the parsing time for a single image is 0.9 s.The repeated precision of the particle size measurement is around ±1%,and the error compared with the micrometer measurement is around ±3%.The proposed method can be used to structure vision feedback control system to granulator for realizing the closed-loop control of particle growth.
Keywords：rotary drum granulation;image analysis;particle size
