Pneumatic jig: effect of airflow, time and pulse rates on solid particle separation

Abstract: This paper aims to provide insights into the factors contributing to the efficiency of separation of solids particles in pneumatic jigging. A batch pneumatic jig was constructed at the University of Nottingham, UK, for solid waste recycling. Synthetic materials (density tracers), colour coded for density, were used as the bed materials in a series of experiments. The bed was analysed layer by layer using image analysis technique, utilizing colour difference among density tracers to calculate separation efficie… Show more

“…These issues motivated the study of recovery behavior of jig by means of modeling and simulation tools. As pointed out by Dong et al [4], there are several benefits to modeling jig: plant design and optimization, experimental design, testing research hypotheses, design and evaluation of control strategies, forecasting, analysis of plant-wide performance, and education [4], [28].…”

“…However, vibration leads to intense movement of particles in the layer, which contributes to unwanted abrasion of the particle surface. Work [16] shows that the pulsating supply of air flow to the layer suspended on the gas distribution grate increases the efficiency of separation. However, the authors of [16] note the importance of selecting the optimal range of pulsation frequency.…”

“…The Euler-Lagrange model (ELM) have a wide use in present-day engineering [3], [7], [21]- [25]. In this contribution, special attention is paid to calculate the water flow in an Euler coordinates where the particles are moved individually in Lagrangian frame.…”

“…They include feed water rate, amplitude and frequency of oscillating flow, etc. [6], [7] When oscillating flow reach low amplitude levels of water velocity (ul<0.001 m/s), undesired concentration occurs [6], [7]. On the other hand, high amplitude levels of water velocity (ul>0.01 m/s) contribute to the acceleration of mineral particles and may inhibit the particle settling.…”
