用尖缩溜槽组模拟圆锥选矿机的研究

Study on Separation of Tapered Concentrators Using Shrinkage Chute Group

圆锥选矿机处理量大,但试验条件比较复杂,制约了其推广应用。通过分析圆锥选矿机和尖缩溜槽的原理、特点,对尖缩溜槽进行优化,并将某钒钛磁铁矿选厂采用的3DS6FD圆锥选矿机与依照3DS6FD圆锥选矿机的内部流程段数配置优化后的尖缩溜槽组进行对比试验,结果表明在实验室中可以用优化的尖缩溜槽组替代圆锥选矿机进行模拟试验研究,用来分析、说明和研究某些低品位矿石是否适合采用圆锥选矿机来处理,以及探索、优化某些老厂推广应用圆锥选矿机的技术改造的可行性。

Big capacity is advantage of tapered concentrators,but one disadvantage of application of tapered concentrators.Analyzed the principle,characteristics of tapered concentrators and sharp shrinkage chute and optimized the sharp shrinkage chute.Comparative tests have been done between the optimized sharp shrinkage chute group according to the 3DS6FD tapered concentrators In the laboratory and 3DS6FD tapered concentrators in one titanium magnetite factory.Results indicate that in the lab the 3DS6FD tapered concentrators can be replaced with optimized sharp shrinkage chute group to study,analysis,description and study some minerals beneficiation of low grade ores being suitable or unsuitable for using tapered concentrators to handle.And whether application of tapered concentrators could be used or not be used for optimizing and exploring mineral processing technology in some old plant.
