Studies and Research Concerning the Displacement of Solid Particle on an Oscillatory Flat Surface

Abstract

The article shows how the operating parameters of a machine used for the separation of a heterogeneous mixture of solid particles affect particle residence time on the working surface in use, the distance followed, respectively the travel speed. Experimental determinations were performed in the laboratory on a stand which working surface runs an alternative oscillatory motion. In the experimental measurements there have been used real particles, respectively small grain beans. Stand parameters which were considered were the angle of the swing plane surface (5o, 7o and 10o) and the crank speed (91, 240 and 405 rpm). As a result of the analysis it was found that between the functional parameters of the working stand (the distance travelled by the particle oscillating solid surface, the time in which the particle follows the distance used as a reference, the linear velocity of the solid particles on the travelled distance) are closely related.

Influence of Screening Block Supporting Way on the Behaviour of a Solid Particle on an Oscillating Surface

“…The supporting system plays a very important role in this process, and this influence has been analyzed analytically by applying different calculation methods [7,9], experimentally for different types of sieves [10,11] and stimulating methods, but also by using simulation programs [12][13][14][15][16].…”

Theoretical Aspects on the Movement of Plant Fragments on the Surface of a Plane Sifters Classifier

“…Characteristic of these sorting surfaces is that particles movement on the sifter surface takes place in jumps [8][9][10]. This is advantageous, since the descendant trajectory of the particle approaches the normal to the surface of separation, facilitating the passage of particles through the holes [11][12][13][14].…”
