ADVANTAGES:
---IMPORTED SKF BEARINGS;
---IMPORTED ROTATING JOINT;
---ADOPT DYNAMIC BALANCE TO THE PULLEY, IT CAN WORK MUCH MORE STABLE;
---SPRAY TWO TIMES ANTI-RUST PAINTS, SO IT WON'T RUST ALL THE TIME;
---316L STAINLESS ROLLER ETC HIGH QUALITY MATERIALS;
---BUILD IT STRICTLY ACCORDING TO THE ORIGINAL KNELSON CONCENTRATOR'S PRINCIPLE......

Ghana 200t/h Alluvial Gold Ore Project, which is invested by Australia client, they buy complete set washing plant from us, after this project, they place another 100t/h alluvial gold plant to us, total amount is more than $360,000.



Features

1. High concentrating ratio and high recovery
2. Total process automation, steady recovery performance
3. Center dischange design for fast, secure concentrate removal
6. Low production costs, durable wear parts, minimal maintenances requirements
7. Compact design requiring less space, easy merged into the existing mining processing
8. Quick payback on investment, typically lass than half year
We build different model knelson conentrators for your different capacity


Descriptions

Centrifugal 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.

Laos 100t/h alluvial gold ore project with GT1848 trommel screen and STLB80 gold centrifuge from us, get 98% gold recovery ratio.





Centrifugal Concentrator was patented in China. It is efficient equipment for 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). It can be used not only for placer gold mining, but also for hard rock mining to recover the natural gold, replacing amalgamation, and recover gold from the old 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 0.04mm in particle size, the gold recovery is 97%.

Alluvial placer gold sand ore washing plant, is for gold ore without clay


Provide high quality, best service and competitive price mining plants with flowchart and design diagram. Such as shaking table, jig, gold trommel, gold sluice, rotary screen, sand washer, spiral chute etc which passed ISO9001:2008 Certification. 

Gold Ore with clay need to use rotary scrubber for washing
