ABSTRACT:
A concrete reclaimer having a pair of concentric mesh cylinders for separating wet concrete into its original components. The invention includes a hopper and feed screw for feeding wet concrete into the inner cylinder at a constant rate. The concrete is washed by a water spray as it passes through the cylinders. The inner cylinder is made from coarse mesh which allows sand and cement, but not gravel, to pass through. Gravel is deposited from the outlet end of the inner cylinder. The outer cylinder is made from fine mesh, allowing cement, but not sand, to pass through. Sand is deposited into the bottom of at least one dewatering screw, which allows water to drain as it elevates the sand. The dewatering screw is in thermal contact with a heated liquid tank to prevent the water from freezing. The cement is dropped through the outer cylinder into a series of settling ponds, where it is allowed to settle out of the water.
