Fig. 9. Velocity of solid particle on surface oscillating<br />

4. Conclusions<br />

The separation of solid particles after size is a complex process<br />

influenced by several factors, which depend of the particles and characteristics<br />

of equipment used.<br />

In the experimental measurements were used real particles and from<br />

analysis of the Triplot chart shows that particle is used as lamellar particle.<br />

Because tyrants, stand used in the experimental determinations executed<br />

oscillations along three axes.<br />

By using two video cameras with purpose to tracking the solid particle<br />

trajectory was be achieved, with help of SynthEyes program, obtaining a threedimensional<br />

trajectory.<br />

Also from experimental data could determine the variation of solid<br />

particle velocity on the oscillating surface.<br />
