Abstract
Seed pelletizing can effectively increase the seed size. However, observing the microscopic process of seed pelletizing using physical tests is challenging. This study used the discrete element method (DEM) to simulate the process. Discrete elemental simulation models and contact parameters of seed and powder had been determined by particle scaling theory and parameter calibration tests, respectively. The contact model (modified model) between the seed and powder was established, which could effectively characterize the effect of the water addition on the viscosity. The seed pelletizing numerical simulation test was carried out with the average number of contact particles as the main evaluation index. The results showed that the amount of powder adhering to the surface of individual seeds was 43. Bench test results show that the quality of pelletized seeds met relevant criteria.
