The guidelines which are at the base of the definition of a system capable of operating on a slurry containing the solid particulate for its characterization are described. All the considerations have been developed with particular reference to the case of a granular heterogeneous material in particular, the different research problems, making a comparison with the case of static images, acquired under laboratory conditions, are pointed out. Attention was focused on problems of acquisition and digital image processing to obtain information which is clean from noise and errors. The considerations and procedures analysed show general validity and can be applied to a large number of problems linked to the “on‐line” morphological characterization of particulate solids materials. Some results for morphological characteristics of lead sulphide (PbS) samples are reported.
