南非的弗拉赛·钱尔麦斯公司(Frasser & Chalmers Ltd)制成了第一台移动式重介质选别装置,以满足地质勘察队进行小型研究试验的要求。这种装置由三个部分,即湿式迴转洗料器、D.S.M.型重介质选矿装置和传动部分组成。每一部分均安在轨道上,很容易变动,这样灵活联接,因而可以在几分钟内根据任务联接而成。图1是选别砂砾、金刚石和红柱石时的最好配置情况。这种装置还可以选别矿石,如含金刚石的云母撖榄岩、萤
Frasser & Chalmers Ltd in South Africa made the first mobile HDM unit to meet the requirements of the Geological Survey team for small-scale research trials. This device consists of three parts, namely, wet rotary washer, D.S.M. type heavy medium beneficiation device and the transmission part. Each part is in orbit, it is easy to change, so flexible connection, which can be based on the task within minutes connection. Figure 1 is the best choice when sorting grit, diamond and andalusite. This device can also choose ore, such as diamond-containing micaceous plutonium, firefly
