The Response of an Uniform Jig Bed in Terms of the Porosity Distribution

At the Faculty of Mining and Petroleum Engineering, the Department of Raw Materials Technology, a mathematical model has been developed to predict the porosity distribution in an uniform jig bed. If the porosity distribution in an uniform jig bed is known, it is possible to correlate this to the settling velocity of particles with a density different from the density of the bed grains and thus model the stratification in a jig. For measuring the porosity distribution in the jig bed a method has been developed based on light absorption techniques.
