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

Beneficiation spiral chute integrates features of spiral concentrator, shaking table, and centrifugal separator. It the best equipment for mineral processing, especially used for mining sands in coastal, river, sand beach, river road, etc. Beneficiation spiral chute is adapted to process alluvial deposit, especially flat materials with high monomer dissociation degree of useful minerals. Besides, since minerals containing high mud have low concentrate quality, so they must be de-slimed and graded before entering into the beneficiation spiral chute. The working features of beneficiation spiral chute is that the concentrate, middling and tailings are gotten at the end of the equipment, and the sorting process does not need washing water. Spiral chute is the main component of the device, which is made of polyurethane wear-resistant plastic or mixed artificial corundum resin. Its liner is made of FRP a wear-resistant material. On the top end of beneficiation spiral chute, there is a mineral separation device and a feed tray; at the lower part of beneficiation spiral chute, there is a products interceptor and a trough for receiving ores. The whole equipment by pioneers manufacturer stands vertically though still frame.

Our advantages: 1. High efficiency: in crushing, it adopts traditional two-stage and a closed circuit system for ideal fineness. Besides, jaw crushers have large crushing capacity. 2. Saving energy in grinding and classification, with characteristics of large processing capacity and small floor area, superfine lamination autogenous mill can save energy by more than 85%. 3. Good classifying effects :in classification, hydrocyclone and vibrating screen can enhance the classifying effects. 4. Environmental protection :i t adopts the third generation tailings dry stacking technology, which can save energy by 60-80%. Furthermore, it can also protect the environment and build a base for green mine. Production technology: Raw material ores is exploited from mountain are big size, so it is necessary to crush firstly, in this process, the raw materials will be feed into primary crusher by feeder, then come into secondary crusher.The materials will go into screen after first and secondary crusher, the suitable size material (â?¤25mm) will go to next step. Oversize(ï¼?25mm) material will go back to secondary crusher to crush again. This forms a closed crush circuit. In this process, material will be grinded into suitable sizes (about 200 mesh) for beneficiation.After grinding material will come to classifier. In classifier, suitable size material will go to next step. Coarse material will go back to ball mill for grind again. This process is a closed grind circuit. In this process, materials will be separated by flotation, magnetic separator or gravity concentrating machine. We will get the materials that we need. Process introduction: after beneficiation, there are some residual water in ore concentration. So we have to carry on concentrate dehydration to meet the requirements of transportation and smelting.

1.Spiral chute is to make seperations of useful minerals from gangues by use of the different particles to gravity hydraulic pressure and friction in the multi-force field through dynamic contrifugal flowing membrane of slurry produced on the inclined surface of spiral based on the differences of useful mineral and gangue in specific gravity,particle size and shape. 2. Spiral chute (glass fiber reinforced plastics spiral chute) is applicable to metal and non-metal ores with adequate density difference, like iron, chromite, pyrite, tin ore, tungsten, tantalum, niobium, gold ore, colliery, monazite, rutile and Zirconium.

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.
