Mechanical Reclamation Treatment of Used Silica Foundry Sand at Extra-low and Ambient Temperatures
Keywords:foundry used sand, mechanical reclamation, cryogenic reclamation, sand testing, waste minimization.
The article presents a short study of the mechanical reclamation techniques implemented in industry and of a research conducted at AGH-UST aiming at intensification and improvement of the mechanical reclamation processes by using extra-low temperature environment. In the paper, the laboratory stand and the results of mechanical reclamation of used foundry silica sands with bentonite and water glass binder, carried out at both extra-low (about minus 70 °C) and ambient temperatures, are presented. The obtained results were evaluated and compared with data taken from the foundry practice.
