Arrangement for determining the particle size distribution of a particle mixture

摘要

The arrangement has an electrooptical measurement path, a particle delivery arrangement for separating particles in a flow and performs digital electronic acquisition of the projection surface. A computer converts the digital information into a particle size measurement. The image acquisition device consists of a number of electrooptical image recording devices (18,19) directed towards the particle flow (15) and with different imaging scales related to each other so as to cover the entire measurement region
