鞍钢弓长岭选厂5～8系统阶段磨选流程中的离心机,对细粒级及粗粒连生体的回收能力低,导致选矿回收率低。1989年选用赣州有色冶金研究所发明的φ1000立环脉动高梯度磁选机后,一改前貌,与现场的φ1600×900离心机进行了分流对比试验,在给矿条件基本相同的条件下,立环机比离心机作业分选指标,铁精矿品位提高4.12％,尾矿品位降低10.16％,回收率提高19.65％ 1990年4月,鞍钢矿山公司与我所及赣州有色冶金机械厂签订合同,于1991年进行
Centrifuge in the milling process of 5 ~ 8 system at Anshan Iron & Steel Changling Plant, which has low recovery ability for fine-grained and coarse-grained organisms, resulting in low dressing recovery rate. After the selection of φ1000 vertical ring pulsating high gradient magnetic separator invented by Ganzhou Institute of Nonferrous Metallurgy in 1989, it changed the front view and compared with the φ1600 × 900 centrifuge in the field. Under the condition of basically the same ore feeding conditions, Vertical ring machine than centrifuge operation sorting index, iron concentrate grade increased 4.12%, tailings grade reduced 10.16%, 19.65% recovery rate April 1990, Anshan Iron and Steel Company and I and Ganzhou Nonferrous Metallurgical Machinery Factory signed a contract , Carried out in 1991
