由赣州有色冶金研究所和中南工业大学联含研制的SLON-1000立环脉动高梯度磁选机在马钢姑山铁矿进行工业试验,分选200目占90％左右难选细粒红矿,至今年2月6日,累计带矿运行1700 h,设备操作简单,运转可靠,选矿富集比大,未发生过磁介质堵塞现象。该机转环立式转动,无须密封,水反冲精矿;配置了脉动机构,运用高梯度磁力,脉动流体力等多种力场的综合效应进行分选,有利于细粒矿物的回收和提高精矿品位,防止介质堵塞。
An industrial experiment was conducted at Magang Gushan Iron Mine with SLON-1000 pulsating high gradient magnetic separator jointly developed by Ganzhou Institute of Nonferrous Metallurgy and Central South University of Technology. About 200% February 6 this year, with a total of 1700 h mine operation, the equipment is simple, reliable operation, beneficiation enrichment ratio, no magnetic medium blockage phenomenon occurred. The turntable of this machine rotates vertically without sealing and water recoil concentrate. The pulsation mechanism is equipped with the comprehensive effect of high-gradient magnetic force and pulsating fluid force and other kinds of force fields for sorting, which is good for the recovery of fine-grained minerals and Improve concentrate quality, to prevent media blockage.
