This article investigates the combined effect and the order of influence of feed rate, inclination angle, vibration amplitude, frequency, and angle on the efficiency and mesh wear rate of a linear vibrating screen, as well as the average velocity, and mass of the accumulated particles. The discrete element modeling simulations were conducted using LIGGGHTS open-source code to analyze particles behaviour. The Taguchi method was employed to evaluate the combined effect of the parameters. Finally, the simulation results were analyzed using analysis of variance. The optimal values of the parameters for maximising efficiency and minimising mesh wear were determined using grey relational analysis. The results indicated that the most effective parameters on screening efficiency and average velocity of particles were the inclination angle, vibration angle, frequency, amplitude, and feed rate, respectively. The most influential parameters on screen mesh wear rate were feed rate, inclination angle, vibration angle, frequency, and amplitude, respectively.
