Gold Concentrators At Kellyco Gold Prospecting Equipment

The gold concentrator primarily uses a cone tube in the heart of the machine. The material is fed into the base before being forced to use power from a motor. The G-force that is created as a result then allows the gold to be separated from the other material, thanks to the natural weight difference. The gold can then be collected with ease after the gold concentrator has finished processing.
