The article determines experimentally the impact of the changes in the surface tension and the degree of the wetting liquid jet break-up and the final moisture content of the bed on the changes in the particle size distribution of the granulated product during the process of the wet drum granulation. Silica flour was used as the experimental material. A change in the surface tension of the binding liquid (distilled water) was achieved by using the Rokanol L4P5 surfactant.
