Applied for years, vibratory conveyors are well established in many industrial processes. Despite frequent use their design is still mostly based on practical experiences. A prototype apparatus was specially developed to perform the experiments within a large range of adjustable parameters. Detailed investigations of the transport properties of coarse sand layers in the size range of 0.2 y remained constant. In other words, the points representing the growth of the mixing layer thickness collapsed on the same curve. The mixing was found to be distinctly depending on h*, increasing h*>1 (i.e. the trough fully covered by particles) strongly reduces the dispersion phenomenon.
