Abstract：Powder filling is a very difficult process because of the poor fluidity and small size. The blanking tube will be blocked if powders quantity is too much at a time in automatic filling process.To solve this problem, a stable filling method based on vibrating screen was put forward. The model can guide and optimize the related parameters settings. The experimental study based on the solving parameters was carried out to verify the effectiveness of the model. The result shows that the amount of particles is mainly related to the amplitude and vibration frequency of the vibrating screen. When the vibration frequency is 3 Hz, and the amplitude is 20 mm, the mean value of the dose is within the expected target, and the control effect is better. According to the parameters of the amount of material control test, the error is about 7%, and less float.
