Sažetak

The results of the investigation results of the granulation process of foundry dusts generated during the mechanical reclamation of spent sands with bentonite and also dusts from the sand processing plants are presented in the paper. The following parameters of the final product were determined: moisture content (W) and granules shatter test (W_z) performed directly after the granulation process and after 1, 3, 5, 10 and 30 days and nights of seasoning, water-resistant ability of granules after 24 h of immersing in water, surface porosity e_p and volumetric porosity e_v. In addition the shatter test and water-resistant ability of granulated products dried at a temperature of 105°C was estimated.
