Abstract:
      Based on the current demand for large production raw grain vibration cleaning sieve, combining TQLZ180×200 type grain vibration cleaning sieve, the structure of large production raw grain vibration cleaning sieve was improved. EDEM discrete element analysis software was used to simulate the screening process of vibration sieve, and the influences of process parameters of vibration sieve on the screening effect were analyzed, then the relationship curves of process parameters and screening effect were established. It concluded that when the vibration frequency of vibration sieve was 14 Hz, amplitude was 3.5 mm, vibration direction angle was 35°and the sieve surface inclination was 6°,the screening effect was the best.So it provided the basis for the further study on screening effect analysis and parameter setting of vibration sieve.
