ABSTRACT:
A material separator for separating at least two different materials of differing densities and/or sizes of particles. The material separator generally includes a tank containing a flocculent, a circulation system for circulating flocculent within the tank and a pair of conveyors for moving two different materials out of the tank. The tank may include an upper chamber and a lower chamber. At least a portion of each of the conveyors is located in the upper chamber to catch materials fed into the flocculent. Each of the conveyors may include a mesh belt that permits the flocculent to flow through the conveyor. The tank may include a clean out valve that permits fines and other debris accumulated within the upper chamber to pass into the lower chamber. The flocculent circulation assembly may include a nozzle that can be constructed in various configurations to create flows of flocculent of various velocities and trajectories. In one embodiment, the lower chamber includes a drag line assembly that removes fines and other accumulated debris from the lower chamber.
