| Abstract: | Based on the dry dispersion principal,dry dispersion mathematical model was analyzed and simulated.According to the gas dynamics and related mechanical circuit principle,a kind of automatic controlled dry dispersion system was designed,including sample and vibration device,gas jet and collection device,gas transmission device.The results show that the most important factor of influencing particle dispersion is the airflow velocity.In the process of dispersion,the sample and vibration frequency,the moving rate of particles and airflow velocity are controllable.The results of this system can achieve expected dispersion effect. |
