在选金溜槽内均装有挡板,用以激起较强的涡流并阻流重矿物,陆地选金溜槽的给料粒度大(达数10毫米),常采用直条挡板或者横条挡板,用圆木、方木或角钢制成,高度较大,间距40-75毫米,在松散的矿层的同时兼有对粘土团的碎散作用,采金船溜槽的给料粒度小,(10余毫米),常采用钢丝编制网或冲割拉板网作挡板,典型的挡板形式。为了避免细粒金流失,当挡板和网格下面还常铺置压纹的橡胶垫,苇席等粗糙铺面物。
In selected Gold chute are provided with a baffle, to arouse strong eddy current and resistance flow of heavy minerals, land selection gold chute feed size (up to several 10 mm), often used straight baffle or horizontal baffle, made of logs, timber or angle, greater height, spacing 40-75 mm, in loose deposits of both at the same time on the ball of clay shattered role, mining of gold dredger chute to particle size small (more than 10 mm) is often used steel wire woven mesh or blunt cut and pull plate mesh baffle, typical of the baffle. In order to avoid the loss of fine gold, when below the baffle and a grid often laying rubber mat embossing, rough pavement material mat.
