Descriptions Centrifugal gold concentrator is a relatively new type of gravity concentration apparatus. The machines 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 was patented in China. It 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.
Application shows that the recovery can be as high as 99%, and the concentrating ratio is up to 1,000 times. In recovering the natural gold in lode ore with size -0.074mm, the gold is up to 98%, For 0.004mm in particle size, the gold recovery is 97%.
1 High concentrating ratio and high recovery; 2 Steady recovery performance; 3 Center discharge design for fast,secure concentrate removal; 4 Environmentally friendly(requires no chemical additives or reagents); 5 Low water and electricity requirements; 6 Low production costs, durable wear parts, minimal maintenance requirements; 7 Compact design requiring less space, easy merged into the existing mining processing; 8 Quick payback on investment, typically lass than half year.
Our company developed automatic discharging system, now our new concentrators can be fully automated for washing. No longer needed wash concentrates by manpower, only needed push start and stop buttion on the antomatic control system to complete all works. Because whole process is closed operation, it can avoid man-made concentrate loss. Besides, our concentrator adopt soft materials at shock-absorbing places, it can effectually decrease negative effects issued from the vibration, and increase of service life.
【Capacity】 0-100 T/H 【Feeding size】 0-6mm 【Processible Material】：alluvial gold, rock gold after grinding, and other precious metals 【Type】vertical auto discharging centrifuge and vertical type manual discharging centrifuge
The Gold Centrifugal Concentrator is a brilliant gravity separation equipment widely used in the mining industry, especially for the placer gold, fine grain rock gold, and other precious minerals. 【Modes】(1) Timed automatic discharge centrifuge, customizable, higher efficiency, higher price. (2) Non-automatic discharge centrifuge, common use, in stock, manually stop working and take out the gold concentrate after few hours of operation. We have it both in industry type and laboratory type small centrifuge. (3) Customized fixed centrifugal concentrator and mobile concentrator (mobile gold wash plant usually equipped with portable trommel screen, portable gold centrifuge, portable gold shaker table, etc). 【Brand】 Knelson Concentrator, JXSC gold concentrator is the best replacement for Knelson Concentrator with affordable price, complete models, wide capacity range. 【Related product】 Feeding: slurry pump or gravity flow by the height difference After gold centrifuge: tailing ⇒ sluice box; concentrate ⇒ shaker table or amalgamator 【Gold Concentrator VS Jig Concentrator】 Centrifugal gold concentrator is easier debugging, and gold safer. It only can take out the gold concentrate after 4-6 hours of continuous work
【Main parts of centrifugal concentrator】feeding, rotor, groove, motor, backwash water, PU lining plate, bearing, frame, tailings and concentrate discharge, etc. 【Working principle of centrifugal concentrator】 The rotor of the centrifuge rotates at a high speed. Under the action of centrifugal force, heavy minerals are stacking on the inner plate groove of the rotor cone, and the light ore particles are gradually discharged. After about 4-6 hours of operation, stop feeding, and turn on the backwater to wash out the gold concentrate. Gold centrifugal concentrator is useful in the gold recovery in all ranges of particle size. It is most especially useful for recovering fine gold which gets lost during the operation of gravity concentrators. The application has shown that the recovery of gold can be very high, as much as 99% and the concentration ratio is up to 1,000 times. In the recovery of natural gold in lode ore that has a particle size of -0.074mm, the gold recovered is about 98%, for recovery of gold in particle size of 0.004mm, it is up to 97%. 【Gold mining equipment manufacturer】 JXSC supply alluvial gold mining equipment for more than 30 years, produces different types of gravity separators, includes gold centrifugal concentrator, shaking table, spiral separator, jig concentrator.

The gold centrifugal concentrator used in combination with the vibrating chute, gold shaker table, gold wash plant and other gold extraction equipment to increase the fine gold recovery rate
The Gold Centrifugal Concentrator is a kind of gravity separation equipment, industrial centrifuge widely used in gold panning industry for placer gold mining, but also for hard rock mining of natural gold, and also for recovery of gold from tailing. It is usually used in combination with the vibrating chute, gold shaker table, gold wash plant and other gold extraction equipment to increase the recovery rate
The main parts of gold concentrator includes feeding pipe, drain pan, main shaft, spring, motor, tailing discharge mouth, belt. high-speed pin create power centrifugal force, in the process of gravity separation, light material would be discharged, gold gathers. Nowadays, the centrifugal concentrator is widely used for the recovery of gold, tungsten, lead, manganese, iron, etc. Gold centrifugal concentrator was patented in China. As a homemade gold separator, It is popular at home and aboard. Gold centrifugal concentrator is useful in the gold recovery in all ranges of particle size. It is most especially useful for recovering fine gold which gets lost during the operation of gravity concentrators. The application has shown that the recovery of gold can be very high, as much as 99% and the concentration ratio is up to 1,000 times. In the recovery of natural gold in lode ore that has a particle size of -0.074mm, the gold recovered is about 98%, for recovery of gold in a particle size of 0.004mm, it is up to 97%
The equipment is actuated by driving shaft driven by electrical motor in belt. which can guarantee the cone rotate in high speed. Ore pulp is discharged into the selecting cone via feeding tube and the selection procession in the concentrator is intensified under the force of centrifuge. The heavy mineral is left in the cell of the selecting cone, the light minerial is discharged outside after being processed by the tailing sluice. After long time operation of every shift, the finished ore will be discharged from the outlet when the concentrator stops working
1). High concentration ratio, which can reach 1000-3000 times, small concentrate productivity, generally 0.02%-0.1%, high concentrate grade, normally, 1000-20000g/t. Compared with conventional gravity dressing machine, the recovery is improved significantly
4).High activity rate, low power consumption ,high automation, low cost. The equipment has high running rate and low power consumption,which is easy to operate. High automatic level and easy to maintenance will cut the production cost
