Abstract: The particle separation process based on high-performance MATLAB/Simulink software was simulated, with an example of simulating the sieving process of vibrating screen. The simulation model of the sieving process of vibrating screen (SMSPVS) was set up， the mathematic models and main Simulink blocks adopted were introduced. The simulation experiment shows that the simulation result is close to the same with actual result， the relative errors between simulation result and actual result of oversize and undersize are -4.26％ and 1.09％, respectively. The process of sieving is accurately simulated by SMSPVS， hence the feasibility of building computer simulation model based on Simulink is demonstrated.
