往复式重选机械设备是针对沙金矿选取过程中泥土、胶泥含量大重矿物含量高，沙石料和重矿物在增金草上容易板结的现象而生产出的一种新型重选机械选金设备。 

The reciprocating gravity separator is a new type of gold dressing equipment for the selection of sand gold ore, which is characterized by high content of clay and clay, high content of heavy minerals, and easy bonding of sand and stone materials and heavy minerals on gold growing grass.

 

重选机械往复重选溜槽与普通溜槽区别： 

   众所周知，沙金矿的选取是一个不断富集的过程，但是在富集的过程中容易造成沙金的丢失，沙金的水选是靠物料比重的不同在水流的过程中重矿物的自然沉降，但是含泥量较高的沙石料如果用水量过大重矿物还没有来得急沉降就随沙石料一起被冲走，从而得不到有效的回收，如果减少水量则会造成沙石料板结增金草堵塞，这也会大大降低沙金的回收率。 

   重选机械往复式重选溜槽的问世解决了沙金矿含泥量高用水多的问题，有效地提高了沙金的回收率，尤其是增金草不容易捕捉的面金回收率尤为明显。

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.


重选机械设备的工作原理： 

    重选机械中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。重选机械设备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。
