80年代末随着大型采金船的引进,锯齿波跳汰机随船引进国内。这是一种具有锯齿波脉动跳汰曲线、高效节能先进的重选设备。对宽级别入选物料适应性强,对中细粒级选别效果好,回收率高,筛下补加水比普通跳汰机省70％以上,采用液压技术省功率60％。广泛应用于采金船、砂矿、赤铁矿、钨、锡、锑和金刚石矿等的选矿。 In the late 1980s, with the introduction of large-scale gold mining vessels, sawtooth jig was introduced into the country with the ship. This is a sawtooth pulsating jigging curve, energy efficient advanced reselection equipment. It has good adaptability to selected material of wide level, good effect on medium and fine grade sorting, high recovery rate, more than 70% of ordinary jigging by adding water under sieve, and 60% by hydraulic technology. Widely used in gold mining vessels, sand, hematite, tungsten, tin, antimony and diamond ore beneficiation.
