The gold centrifugal concentrator is a gravity-enhancing device. The feed slurry is introduced into a rotating drum, and the impeller rotates to form a high-gradient centrifugal field. The ore particles flow on the inner wall of the rotor and are continuously layered and deposited on the smooth inside the centrifuge wall.
Sep 30, 2015 Here is how a gravity gold concentrator (centrifuge) works as a separator Make sure the concentrator has been correctly assembled and that all bolts have been tightened. If required, attach a funnel to the material feed inlet. If necessary, connect a hose to the tailings outlet. Place the concentrator on a raised structure such as blocks.
