09-07-2015· Screening efficiency can be expressed relative to oversize (Eo), undersize (Eo), or overall (E). The following equations are used to calculate each of these respectively: Eo = [Qms(o) X (1 Mu(o))] / [Qms(f) X (1 Mu(f))] Eu = [Qms(u) X Mu(u)] / [Qms(f) X Mu(f)] E = Eo X Eu or combined: E = [Qms(o) X (1 Mu(o)) X Qms(u) X Mu(u)] / [Qms(f) X (1 Mu(f)) X Qms(f) X Mu(f)]

A very important factor to an effective Whole Body Vibration machine is the G-force, or the gravitational load. This is what makes your muscles relax and contract when you stand on the vibration machine. Imagine standing in an elevator. If the elevator suddenly moves downward at a high speed, you will feel like you are floating (muscles relaxed).
Movement of the ore is simulated with DEM to obtain the force over the screen deck, and this force is then used in the calculation of the dynamic model. In this study, a 2D linear model with three degrees of freedom that considers ore inertia and the ore force over the screen calculated using discrete element method is developed in order to determine the influence of the ore on the movement of a vibrating screen.
