摘要：

Flow of water inside a jig has a strong bearing on the rate of stratification of particles, For this reason, various fluid waveforms are proposed for achieving optimal stratification rate. In the present investigation, the flow of water is analyzed in a carefully controlled laboratory jig. In a very simplified manner, the amplitude and frequency of pulsation is controlled by means of the compensator pressure and a level sensor. This allows for proper analysis of the dynamics of motion of the fluid as function of the amplitude and frequency of pulsation. Furthermore, the effects of amplitude and frequency of pulsation on the stratification behavior of the particles is analyzed to establish the existence of an optimal operating condition in terms of amplitude and frequency of pulsation.
