旋流筛是细粒物料的湿式筛分分级设备。于1965年底北京矿冶研究院与我所共同进行过初步试验。其目的是探索用于细粒物料的筛分分级,取代某些细粒物料的分级设备。但由于试验时间短,设备不完善,所以一直未推广应用。针对各锡选厂原矿开路磨矿工艺不适应,近年来原矿锡品位下降,锡石结晶粒度变细,锡铁致密共生等性质的变化,要求各段磨矿的粒度下降,并严格地控制各段的磨矿粒度,以便减少过粉碎和磨不细
Swirling screens are wet-sizing grading equipment for fine-grained material. At the end of 1965, Beijing Institute of Mining and Metallurgy carried out preliminary tests together with our institute. Its purpose is to explore the grading equipment for the classification of fine-grained materials to replace certain fine-grained materials. However, due to the short test time and the imperfect equipment, it has not been popularized. In view of the fact that the open ore grinding process of each ore dressing plant does not meet the requirements, in recent years, the grade of raw ore decreases, the grain size of cassiterite becomes narrower and the compact symbiosis of tin and iron changes, and the grain size of each section of grinding is required to be reduced and strictly controlled Segment grinding particle size, in order to reduce the over-crushing and grinding is not fine
