工作原理： 

    重選機(jī)械設(shè)備重選溜槽的工作原理是利用機(jī)械運(yùn)動(dòng)振頻改變礦粒的自由沉降為干涉沉降的原理，使礦粒之間產(chǎn)生不斷的碰撞從而造成低密度礦粒沉降速度降低。機(jī)械往復(fù)運(yùn)動(dòng)和半阻流式翻漿板使沙石料進(jìn)入載有選金毯或增金草的溜槽時(shí)首先起到勻漿的效果，然后利用機(jī)械的沖擊頻率使重礦物快速沉降并且按照礦物比重的不同產(chǎn)生不斷的替換，使沙石料中比重最大的礦物始終保持在增金草內(nèi)部。半阻流式翻漿板起到減緩大比重礦物順流的流速，相對(duì)于比重小的沙石料在機(jī)械運(yùn)用和阻流板的作用下產(chǎn)生不斷的翻滾，所以不會(huì)因?yàn)樯呈虾嗔扛叨谠鼋鸩萆习褰Y(jié)。 

   The difference between the reciprocating reelection chute and the ordinary chute: 1
 As everyone knows, the selection of sand gold enrichment is a continuous process, but easily in the enrichment process caused by the loss of gold, gold water by proportion of materials of different natural sedimentation process of heavy minerals in the water, but the mud containing high amount of sand stone if there are no more urgent settlement is too large with the heavy mineral sand stone is washed away, so as not to effective recovery, if reduce the amount of water will cause the sand stone compaction by gold grass jam, which will greatly reduce the recovery rate of gold.
 The advent of the reciprocating gravity chute to solve the sand gold high mud content water problems, effectively improve the recovery rate of gold, especially gold grass is not easy to capture the surface of the gold recovery rate is obvious
