三流分选系统的应用和推广是重介质选矿技术的新发展。三流分选器又名 Tri—Flo 是在狄纳旋涡旋流器(D.W.P)的基础上发展起来的。60年代末期,美国选矿公司用狄纳旋涡旋流器作为重介质选矿分选设备,后来传到了欧洲,意大利的马苏阿选矿厂也采用了狄纳旋涡作为重介质预选抛废设备。由于选矿给矿变化很大,氧化矿增多,狄纳旋涡无法在矿石性质变化剧烈的情况下,长期保持合适的分选效率。 The application and promotion of the third-flow sorting system is a new development of heavy medium beneficiation technology. Tri-flow separators, also known as Tri-Flo, developed on the Dina swirling cyclone (D.W.P.). In the late 1960s, the United States beneficiation company Dina swirling cyclone as a heavy medium beneficiation sorting equipment, and later spread to Europe, the Italian Masu Arsenal also used Dina vortex as heavy media pre-selected throwing waste equipment. Due to the great changes in ore dressing, oxidation ore increased, Dina vortex can not change the nature of the ore in the case of dramatic changes in the long-term to maintain the appropriate separation efficiency.
