Resumen:
An experimental study of granular segregation is reported on rectangular grain piles built by dropping
simultaneously grains of two different species from a funnel moving back and forth sinusoidally parallel to the length of
the pile. Our experimental set-up allows us to control the following variables during the build-up of the pile: height of
the injection point above the top, amplitude and velocity of its displacement and injection flow rate for each kind of
grains. Glass beads of different diameters are used in the experiment. Preliminary experimental results demonstrate that
the distance of the injection point from the top of the pile and the amplitude of the motion have the largest influence on
the segregation.
