Abstract

Procedure to determine the distribution of particle sizes in a quantitative stream of granulated material within a range of particle sizes between 1 μm and a few millimeters, characterized in that the stream of material to be analyzed is introduced at a constant speed in the course of a predetermined period of time as the measurement time, preferably in a transverse direction with respect to the flow of a carrier agent stream, also of constant velocity, in this stream, choosing the speeds of the material stream and the agent stream in such a way that the various classes of particles fan out in separate particle pathways from each other, and that the amounts of particles assigned to the various classes of particles are determined in the range of material on the basis of extinction or absorption of electromagnetic radiation.
