Gold Centrifugal Concentrator is a new type of gravity mineral processing device., It can be used not only for placer gold mining, but also for hard rock mining to recover the natural gold, but also used to recover gold from the old tailings. It is widely applied on recovering free gold in all particle size ranges, especially for recovery of fine gold which is lost during the operation of the gravitational concentrators (sluice boxes and jigs).
Test showed that the machine is very effective for separating monomer gold in vein gold deposits as replacement of mercury plate. the recovery can be as high as 99%, The cleaning up cycle is 1~4 hours, and the upgrade ratio is up to 1,000 times. Especially for the case in recovering the natural gold in lode ore with 65% of the ore having a milling size of ¡ª0. 074mm, the recovery for the natural gold is expected up to 98%. For those natural gold of 0.004mm in particle size, the recovery is 97%
The gold centrifugal concentrator can treat particle sizes from below 10 microns up to a maximum of 6mm and is most commonly used for recovery in Gold and Platinum. Other recovery uses include Mercury, Palladium, Tantalum, Copper, Silver and Diamond Indicator Minerals.
Structure and Working Principle
The machine is operated by motor via belt driving draft to make liner rotate at a high speed. Slurries are delivered to liner through feed pipe and are subject to stronger process of separation under the action of centrifugal force. Heavy mineral remains in the lattice chute of liner and light mineral is drained via tailing chute. Concentrate is discharged through outlet after one shift operation and shutdown of the machine.

Centrifugal gold concentrator is a relatively new type of gravity concentration apparatus. The machines of pioneer s stlb series concentrator utilise the principles of a centrifuge to enhance the gravitational force experienced by feed particles to effect separation based on particle density. The key components of the unit are a cone shaped "concentrate" bowl, rotated at high speed by an electric motor and a pressurized water jacket encompassing the bowl. Feed material,typically from a ball mill discharge or cyclone underflow bleed, is fed as a slurry toward the centre of the bowl from above.The feed slurry contacts the base plate of the vessel and due to its rotation, is thrust outward.The outer extremities of the concentrate bowl house a series of ribs and between each pair of ribs is a groove. During operation the lighter material flows upward over the grooves and heavy mineral particles (usually of economic value) become trapped within them. Pressurized water is injected through a series of tangential water inlets along the perimeter of each groove to maintain a fluidized bed of particles in which heavy mineral particles can be efficiently concentrated. Centrifugal gold concentrator is an efficient equipment for recovering free gold in all particle size ranges,specially for recovery of fine gold which is lost during the operation of the gravitational concentrators(sluice boxes and jigs). It can be used not only for placer gold mining, but also for recover the natural gold from hard rocks, to replace amalgamation, and recover gold from the tailings.
Description The centrifugal concentrator, a kind of gravity separation equipment, is suitable for the separation of heavy medium minerals that have enough specific gravity differences. STLB concentrator is kind centrifugal concentration equipment. It can be used not only for placer gold mining, but also for hard rock mining to recover the natural gold, replacing amalgamation. It is also used to recover gold from the old tailings. Since 1985, three models have been developed. Application shows that the recovery can be as high as 99%, especially for the case in recovering the natural gold in lode ore with 65% of the ore having a milling size of 0.074mm, the recovery for the natural gold is expected up to 98%. For those natural gold of 0.004mm in particle size, the recovery is 97%. The cleaning up cycle is 1~4 hours. And the upgrade ratio is up to 1,000 times. Working Principle Water jacket centrifugal concentrator is forced by centrifugal force increases mineral centrifugal acceleration, the minerals in the centrifuge spins a few times to get the equivalent in gravity state, then the proportion of mineral difference is magnified several times, Together with recoil mineral water to prevent compaction, thereby fine, mineral beneficiation achieve good results. Main models: D20 with 1-2t/h capacity D30 with 2-7t/h capacity D60 with 15-30t/h capacity D80 with 30-70t/h capacity D100 with 60-100t/h capacity

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 ).
