The invention relates to a device making it possible to recycle concrete products showing imperfections, at the output of the precasting presses. According to Figure 1, the device consists of an ejector 1 which removes the defective products B from the pallets A and drops them into a receptacle 2. This receptacle is equipped with an extractor having a conveyor belt 3, with a separator 4 which dumps the broken defective products into a mixing screw 5. The reconstituted fresh concrete is taken up by an Archimedian lifting screw 6 and by an Archimedian discharge screw 7 with orientation pivot 8 so as to be recycled in the receiving hopper T of the press P. The device according to the invention is particularly intended for factories producing industrially precast concrete elements. <IMAGE>
