工作原理： 

    重选机械设备重选溜槽的工作原理是利用机械运动振频改变矿粒的自由沉降为干涉沉降的原理，使矿粒之间产生不断的碰撞从而造成低密度矿粒沉降速度降低。机械往复运动和半阻流式翻浆板使沙石料进入载有选金毯或增金草的溜槽时首先起到匀浆的效果，然后利用机械的冲击频率使重矿物快速沉降并且按照矿物比重的不同产生不断的替换，使沙石料中比重最大的矿物始终保持在增金草内部。半阻流式翻浆板起到减缓大比重矿物顺流的流速，相对于比重小的沙石料在机械运用和阻流板的作用下产生不断的翻滚，所以不会因为沙石料含泥量高而在增金草上板结。 

   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
