Gravity separator

摘要

An apparatus, method, and system are provided for separating material. In some embodiments the separator may include a deck. The deck may accept the material to be separated at a feed end and may provide separated output material at a discharge end. The flow of the material along the deck from the feed end to the discharge end may define a feed direction. The deck may be subject to a vibration or conveyance aligned with the feed direction. The deck may include riffles or corrugations. The riffles may be oriented at an angle relative to a direction of the vibration or conveyance, or at an angle relative to the feed direction. The deck may be subjected to an end-to-end elevation or slope. The end-to-end slope may be positive/downhill, negative/uphill, or zero.

主权项

1. A separator comprising:
a deck having a feed end and a discharge end, the deck being configured to receive material at the feed end and discharge the material at the discharge end, and the deck including a flow direction of all material being defined from the feed end to the discharge end, the deck including riffles aligned at an acute angle relative to the flow direction, the deck further including a first side and a second side; a vibration mechanism configured to vibrate the deck, the vibrations including a vertical component and a horizontal component, such that a downstream horizontal component coincides with the flow direction and an upper portion of the vertical component is applied with the downstream horizontal component, wherein the separator tilts the deck such that he first side of the deck is elevated relative to the second side of the deck.
