| Abstract: |
| In order to improve the grading effect of walnut shell and kernel mixture, the existing classification equipment of walnut shell and kernel mixture was modeled by 3D entity, and the grading process of the walnut shell and kernel mixture was simulated by EDEM. Based on the movement speed, mass of the material on the sieve surface and quantity of particles of each grade material in the statistical area as indicators, the grading process by vibrating screen was optimized with the amplitude, vibration frequency, vibrating direction angle and the sieve surface inclination as factors. The results showed that the screening rate of each grade of walnut shell and kernel was the highest and the grading effect was the best under the conditions of vibration frequency 12 Hz, amplitude 5 mm, vibrating direction angle 45°, and sieve surface inclination 4°. |
