Abstract In this thesis,the changes of the circulation-time according to different size particles of the broad size coarse carbamide particles were studied.Experiments were performed in a spouted fluid-bed,with a draft-tube,in different operational parameters.The results show that the different motion tracks of different size particles of broad size materials lead to the different average circulation-time.The motion tracks of large-size particles are shorter than that of little size ones,and accordingly the average circulation-time are shorter with less effects of aeration velocity.In addition,largesize particles grow faster in the granulation experiments of carbamide.
