ABSTRACT The computational fluid dynamics and discrete element method (CFD–DEM) simulation with the discrete particle model (DPM) model was used to simulate the separation process of coarse and fine mixed particles in the cyclone separator. The coarse particle flow trajectory and fine particle mass flow rate change rule were analyzed. Then, the effects of inlet air velocity, fine particle diameter, discharge pipe diameter, and discharge pipe depth on the cyclone separator's pressure drop and separation efficiency were determined. Four‐factor five‐level orthogonal numerical experiments were conducted to optimize the cyclone parameters. The results show that the order of influence factors of the fine particles’ escape rate is the particle diameter, the discharge pipe diameter, the discharge pipe depth, and inlet gas velocity. The pressure drop is, in order, the inlet gas velocity, the discharge pipe diameter, the particle diameter, and the discharge pipe depth. The optimal solution parameters, considering the escape rate and pressure drop, are also examined.
