The experimental stream reclaimer is presented schematically in Figure 1. This reclaimer is characterised by a very simple structure, providing a possibility of applying more crushing elements (in vertical direction), which increases the yield of the reclamation process, of mainly continuous character. In addition, an application of feeders allows a precise control of the amount of the introduced spent moulding sand. This reclaimer enables a proper separation of the reclaimed moulding sand from a dust-air mixture, and the obtained - of full value - raw material can be reused in the moulding sands preparation.
