The preliminary investigations of the mechanical-grinding reclamation of used sands from the alpha-set technology, belonging to a sand group difficult for reclamation, were performed. The new testing apparatus equipped with a rotor system enabling a change of intensity of grinding and crushing influences by selecting shapes of rotor elements and rotational speeds of a rotor system - was applied in the mechanical reclamation. This apparatus enables the used sand reclamation in a traditional vertical system of a rotor and apparatus system or the operation in out of plumb system (from 0 to 6o). This apparatus was made in order to create comparative conditions of used sands reclamations which constitute the basis for comparative assessment of reclaimability of various sands, at not changing reclamation influences. The effects of releasing matrix grains from coatings of binding agents obtained under these conditions are more reliable and the determined effectiveness of the matrix reclamation from various used sands are more likelihood.
