Investigations concerned producing of granules of the determined dimensions and strength parameters.\n\t\t\t\tGranules were formed from the dusts mixture consisting in 50 mass% of dusts obtained after the reclamation of the furane sands and in 50 mass % of dusts from sands with bentonite. Dusts from the bentonite sands with water were used as a binder allowing the granulation of after reclamation dusts from the furane sands.\n\t\t\t\tThe following parameters of the ready final product were determined: moisture content (W), shatter test of granules (Wz) performed directly after the granulation process and after 1, 3, 5, 10 days and nights of seasoning, water-resistance of granules after 24 hours of being immersed in water, surface porosity ep and volumetric porosity ev. In addition the shatter test and water-resistance of granulate dried at a temperature of 105°C were determined.\n\t\t\t\tInvestigations were performed at the bowl angle of inclination 45°, for three rotational speeds of the bowl being: 10, 15, 20 rpm.\n\t\t\t\tFor the speed of 10 rpm the granulation tests of dusts mixture after the preliminary mixing in the roller mixer and with the addition of water-glass in the amount of 2% in relation to the amount of dust were carried out.\n\t\t\t\tThe obtained results indicate that the granulator allows to obtain granules from dusts originated from the reclamations of moulding sands with the furane resin with an addition of dusts from the bentonite sands processing plants.","url":"https://innscience.ca/es/community/literature/fd5488fb-360b-4fef-9b72-5e5d426e1d28"}
