Abstract: A distribution device for separating and orienting particles in a particle stream conveyed by the device to a particle-measuring device, including a conveying device with a discharge at one end for particles that are to pass in free fall to a downstream image-capturing device. At least two conducting elements are associated with the discharge and are movable relative to one another in that at least one of the conducting elements is movable under the effect of a drive mechanism. A feed gap is provided between the conducting elements for separated particles falling out of the discharge. The conducting elements are arranged in the manner of a funnel such that the feed gap is formed at an end of the funnel.
