The investigation results of the reclamation of spent moulding sands with furfuryl resin are presented in this paper. The reclamation

process was performed in the secondary reclamation chamber of the REGMAS 1.5 vibratory reclaimer. 70 kg portions of moulding sands,

previously subjected to the primary reclamation and dedusting, were used. The secondary reclamation was performed in two stages: the

first consisted of determining the reclaimer intensity at various reclamation times (5 min, 10 min and 15 min) and various electrovibrator

frequencies (40 Hz, 50 Hz and 60 Hz), the second consisted of determining the influence of additional crushing elements on the intensity

of processes.
