| Abstract: | To solve the problems of the traditional airflow crushing methods such as low energy utilization,high cost of crushed material,low yield and limit of the scope of material processing,based on the improving of the structure of the nozzle,an new circular compound nozzle was designed to improve the airflow crushing efficiency. Through numerical simulation,it was showed that the new circular compound nozzle had more advantages such as high jet speed,jet relative concentration and far jet range and so on compared with the conventional nozzle. |
