Tray Type Centrifugal Gold Separation Machine LP600 also called gold panning machine in pioneers machinery factory as heavy medium separation appliance, is supported with hollow shaft and driven by power, with its major part being of cauldron disk. Slurry is transferred via slurry pump to the separation disk center where ore grains are acted by both gravity and inertial centrifuging force. During the course of movement by the ore grains upwards along the center of disk surface, when angle is greater than 45 degrees, the centrifugal component force in the direction of slope will gradually decrease while gravity component force will gradually increase. When it is up to a certain level, the two forces will reach balance, and near the point of balance easily develops a heavy mineral sediment layer. Tailings are discharged from edge at the upper disk, and concentrates after stop of feeding ( shut-down), are washed with water before being drained by hollow shaft. The major structure of the machine follows the technical data about gold washing from KNUDSEN, Australian mining company. The machine is primarily applied for washing and separating placer gold at a size of minus 4mm and is capable of recovering natural gold grains at sizes of over 15 um. In operation, inner hole of the center is blocked using plug with its drainage and collection at a regular basis. It can be operated intermittently or continuously, with the ore feeding and water adding simultaneously. The rotation direction is anti-clock( as indicated by arrow) at a speed of 70-110 r/pm. Ratio between solid and liquid for slurry is 1/4-2/3. The machine can be operated by power individually and multi-machines also can be operational in a combined or pedal manner ( without power supply ).
