Abstract

In this paper we present a series of obtained results from the analysis of the behavior of a solid particle on a flat oscillating surface, a process that is found in separation operations of a heterogeneous mixture of solid particles. In this study, the inclination angle of the flat surface (7 or 10 degrees) and the eccentric device speed (91, 244 and 405 rpm) were varied. The results are extracted from video analysis using two commercial video cameras (Sony DCR-SR 36) with a recording speed of 25 frames per second, using the SynthEyes and Mathcad processing software. The obtained results from the analysis helped us to extract data showing the movement on the three axes OX, OY and OZ, average travel distance, average moving time of the solid particle on working surface and average velocity of the solid particle displacement.

Highlights

The researches applied in process industries are very complex and refers to many aspects, from the particle size reduction, heterogeneous mixtures separation and up to energy consumption and processes optimizing [1,2,3].Within the processing industry there are numerous ways to achieve the separation of components of a heterogeneous mix into distinct fractions
In order to identify the behaviour of a single solid particle on an oscillating surface, we used a laboratory stand having a blind sieve as working surface
For the Ox axis we notice that the average value of the distance travelled by the solid particle on the 10 ͦ inclination oscillating surface is higher than the average value of the distance travelled by the solid particle on the 7 ͦ inclination oscillating surface

Summary

Introduction

The researches applied in process industries are very complex and refers to many aspects, from the particle size reduction, heterogeneous mixtures separation and up to energy consumption and processes optimizing [1,2,3].Within the processing industry there are numerous ways to achieve the separation of components of a heterogeneous mix into distinct fractions. One of the oldest and the most used method of separation is the separation according to size, method taking into account the three dimensional elements of a solid body: length, width and thickness [4]. This method is can be found in the facilities used in different processing industries, and in analysis laboratories for solid granular products [5, 6]. This separation method is influenced by a series of factors with regard to the characteristics of the mix undergoing the separation process, as well as to the type of equipment carrying on this process, its operating mode and functional features [7,8,9].
