The HZZD rotary cleaning screen was used as the prototype to establish the simulation screening system model. To obtain the best motion parameters, the discrete element analysis software EDEM was used to analyze the factors affecting the average propelling speed of the particles and the screening efficiency by changing the parameters of the cleaning screen. The analysis results showed that the order of the influence of the factors on the average propelling speed of the particle group was: radius of gyration of the sieve> rotating speed > inclined angle of the sieve surface; To achieve a better screening effect, the radius of gyration should be taken as 20 mm, the rotating speed as 450 r/min and the inclined angle of the sieve surface as 6 to 8.
