Vibrating Screen Science

This paper presents a numerical study of particle flow and sieving behavior on a vibrating screen.The particle flow is modeled by means of discrete element method dem at a particle scale.The dem model is first verified by the good agreement between the numerical and experimental results in terms of the distribution of percentage passing of different sized particles along the screen deck.

These results strongly agreed with the data extracted from a vibrating screen where fractured spring had been working.Fatigue analysis also predicted that the nominal load should be reduced to 90 in order for the spring to meet the minimum life requirements before failure occur.The 6 th international conference on mining science.
