往復式重選機械設備是針對沙金礦選取過程中泥土、膠泥含量大重礦物含量高，沙石料和重礦物在增金草上容易板結的現象而生產出的一種新型重選機械選金設備。 

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.

 

重選機械往復重選溜槽與普通溜槽區別： 

   眾所周知，沙金礦的選取是一個不斷富集的過程，但是在富集的過程中容易造成沙金的丟失，沙金的水選是靠物料比重的不同在水流的過程中重礦物的自然沉降，但是含泥量較高的沙石料如果用水量過大重礦物還沒有來得急沉降就隨沙石料一起被沖走，從而得不到有效的回收，如果減少水量則會造成沙石料板結增金草堵塞，這也會大大降低沙金的回收率。 

   重選機械往復式重選溜槽的問世解決了沙金礦含泥量高用水多的問題，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為明顯。

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.


重選機械設備的工作原理： 

    重選機械中重選溜槽的工作原理是利用機械運動振頻改變礦粒的自由沉降為干涉沉降的原理，使礦粒之間產生不斷的碰撞從而造成低密度礦粒沉降速度降低。重選機械設備往復運動和半阻流式翻漿板使沙石料進入載有選金毯或增金草的溜槽時首先起到勻漿的效果，然后利用機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部。半阻流式翻漿板起到減緩大比重礦物順流的流速，相對于比重小的沙石料在機械運用和阻流板的作用下產生不斷的翻滾，所以不會因為沙石料含泥量高而在增金草上板結。
