concentrators for both alluvial and fine milled hard rock ores. knelson: the best gravity concentrators ever gcaknelson concentrators were the first fluidised centrifuges. every similar product that followed simply copied byron knelsons exceptional concept. as mentioned previously, knelson started out in front and remains so due to numerous design advantages. these include: 1. tangential fluidising (better fluidising coverage, no ratholing, no spray bars and inching drives to flush concentrate) 2. isolation of any rotor vibration from the machine frame and structure, disallowing frequent shutdowns due to excess vibration 3. a vast range of specific, customdesigned concentrating cones for different applications and duties 4. fullyfluidised cones that reduce wear and eliminate particle packing (and resultant unbalanced rotors and vibration) 5. conical water jackets designed to move silt to the top outer edges, ejecting it from the machine rotors 6. continuous research and development see full list on gca.gold the robustness of fl knelson concentrators results in them having both a higher availability and a longer lifespan than competitor products. when spinning a heavilyengineered rotor between 60 and 200 gs, its important to get things right, and that is something that the design team at knelson has done from inception. as such, the machines offer the best availability in the industry and often last for the lifetime of a mine or plant. furthermore, fl knelson concentrators do not regularly shut down on vibration alarms and in fact most knelsons do not need to be fitted with vibration sensors. there are well over 100 machines in africa alone that are over 15 years old, and still delivering concentrate as they have since commissioning. in zimbabwe, a 20yearold knelson was replaced by a competitor machine on the promise of better support from the competitor. within three years, the mine purchased and installed a new fl knelson instead. similarly, there is a mine in z see full list on gca.gold it is not solely durability and availability that brought about the examples above, but also lower operating costs. any machine spinning at extremely high speeds in highly abrasive slurry is bound to wear, and of course knelsons do too, primarily the concentrating cones. however, they dont shake themselves to pieces or transmit vibration to bearings, shortening bearing life, and they dont have unfluidised (and thus unlubricated) zones that inevitably wear quicker. there is a reason we have seen recent changes to competitor devices, such as additions of vibration isolators and changes to outer launder covers, to more closely resemble fl knelsons. again, fl knelson concentrators are leading whilst others follow. in addition, continual development in refining design, user friendliness and reduced operating costs has resulted in continuous improvement to the concentrating cones, the primary wear part. with each generation fl knelson cones become cheaper, easier to see full list on gca.gold the first knelson concentrator was trialled in 1976, 40 years ago, and knelsons have been at the forefront of the industry ever since. through all those years, knelson has been widely accepted as the gold standard of gravity recovery. not long after the first knelson was unveiled, other companies and wouldbe manufacturers picked up on the idea and tagged along. so they have also been around for some time, but 40 years on fl knelson still has over 80% of world market share. again, the facts speak for themselves. in the words of the great byron knelson: unless youre the lead dog, the view never changes. and with the fl knelson concentrator, the constantly changing view is something to be admired. having definitively proved that fl knelson concentrators are not only superior at mineral recovery, but also last longer and have better aftersales service and r&d, the choice for any mining company considering gravity concentration should be simple. if you would like t see full list on gca.gold china gold concentrator, gold concentrator manufacturers china gold concentrator manufacturers select high quality gold concentrator
