在过去的20年中,包括溜槽、螺旋选矿机和圆锥选矿机在内的流膜重力分选设备已有很大的进展,而且这些设备在选别各种细粒物料方面在技术上已非常成熟。当前人们对圆锥选矿机又发生了兴趣,这是因为人们重新认识到这种设备具有高处理能力和造价低的优点,从而可获得效益的缘故。通过对一些此类革新设备应用的观察而重新考查了其特性。高处理能力的此类选别设备的优点也体现在高处理能力的螺旋选矿机上,这种设备同样也具有操作简单、易干选型以及费用低等优点。除了这些优点外,还表明在应用中可获得良好的选别指标。本文介绍了高处理能力的圆锥选矿机和螺旋选矿机的最近应用实例,并提供了有关这些选矿设备的选别数据。
Over the past two decades, great progress has been made in fluid-gravity grading equipment, including chutes, screw concentrators and conical concentrators, and the equipment is technically very selective in sorting various fine-grained materials mature. At present, people are interested in cone concentrator because people re-recognize the advantages of high processing capacity and low cost of such equipment, so as to obtain benefits. Examined some of its features by observing the application of some such innovative equipment. The advantages of such a sorting plant with high processing capacity are also reflected in the high-capacity spiral concentrator, which also has the advantages of simple operation, easy-to-dry selection and low cost. In addition to these advantages, it has also been shown that good sorting indices are available in the application. This article presents recent examples of application of conical concentrators and spiral concentrators with high processing capacity and provides sectoral data on these beneficiation plants.
