The present invention is a novel concrete reclaimer cylinder with a closed chamber and a screen chamber. The reclaimer is disposed in a non-horizontal position such that screen chamber is positioned lower than the closed chamber and driven to rotate. Concrete product is received into the closed chamber at its receiving end and is washed with water to produce cement slurry. The cement slurry is floated out of the closed chamber at the receiving end leaving a mixture of sand and gravel in the closed chamber. The sand and gravel mixture is advanced through the closed chamber by four triangular blades. Each blade is planar in shape, with a perpendicular portion extending from the front edge to direct the sand and gravel mixture through an aperture and into the screen chamber. The sand and gravel mixture is received in a rotating screen and washed by high pressure spray to separate the two constituents. The sand permeates the rotating screen while the gravel remains inside the rotating screen. The cement slurry, sand and gravel are collected in separate containers for future use.
