由江西有色冶金研究所、铁坑铁矿和赣州冶金机械修造厂共同研制的湿式强磁场磁选机为铁坑铁矿的扩建工程和弱磁性铁矿物的选别提供了适用的工业样机。该机在铁坑铁矿选矿厂进行工业试验,已取得良好的结果。用以处理含铁34.45％的褐铁矿,经一次粗选一次扫选的单一磁选流程,可获得品位为50.29％的精矿,铁回收率为70.57％,电能消耗为每吨原矿3.87度,水量单耗3.85吨。采用磁—浮联合流程,铁的总回收率可达76.23％。该磁选机的分选圆环外径为2770毫米,机器总重30吨,处理能力为25～30(吨/时)。本文详细介绍了该机主要结构的特点,包括磁路的选定、冷却方式以及分选室的布置与聚磁介质(齿板)的组装形式等。设计中各种结构参数的选定都经过周密的计算,所以电路、磁路短,漏磁少,功率消耗低,贵重材料省,造价低,运转费用比较经济。文中详细介绍了该机的电磁性能,提供了机器的主要尺寸和技术数据。
The wet magnetic field magnetic separator jointly developed by Jiangxi Nonferrous Metallurgy Research Institute, Tiekeng Iron Mine and Ganzhou Metallurgical Machinery Repair Factory provides a suitable industrial prototype for the extension of Tiekeng iron ore and the selection of weak magnetic iron ore. The machine in iron pit iron ore beneficiation plant for industrial tests, has achieved good results. For a 34.45% iron-bearing limonite, a 50.29% concentrate with a recovery of 70.57% and a power consumption of 3.87 degrees per ton , Water consumption 3.85 tons. The use of magnetic - float joint process, the total iron recovery rate of up to 76.23%. The magnetic separator sorting ring diameter of 2770 mm, the machine weighs 30 tons, the processing capacity of 25 to 30 (tons / hour). This paper describes in detail the main features of the aircraft structure, including the choice of magnetic circuit, cooling and sorting room layout and magnetic media (tooth plate) assembly form. The design of a variety of structural parameters are carefully calculated, so the circuit, a short magnetic circuit, less leakage flux, low power consumption, expensive materials, low cost, operating costs more economical. The article details the electromagnetic performance of the aircraft, providing the main dimensions of the machine and technical data.
