随着国民经济的快速发展,我国钢铁、电力、煤炭等行业也得到了突飞猛进的发展,需要的原料更多,同时对原材料的质量也提出了更高的要求,去除铁磁性杂质的任务也越来越艰巨。我国已构成“布局合理、层次分明、功能齐全”的港口格局。在各大输煤港口码头、电力、冶金、煤炭、建材、矿山、粮食、化工等行业需求量逐渐增多。尤其在煤炭行业中,煤炭中混有雷管及残屑、铁钉等铁杂质,不仅影响煤矿、装货港的安全生产,而且给卸港及用户造成极坏
With the rapid development of the national economy, China’s steel, electricity, coal and other industries have also been by leaps and bounds, the need for more raw materials, while the quality of raw materials also put forward higher requirements, the task of removing ferromagnetic impurities also Yue The more difficult. Our country has constituted a “port layout with reasonable layout, distinct levels and complete functions”. In the major ports of coal transportation ports, electricity, metallurgy, coal, building materials, mining, food, chemical and other industries gradually increased demand. Especially in the coal industry, coal is mixed with detonators, iron scraps and other iron impurities, which not only affects the safe production of coal mines and ports of loading but also causes extremely bad effects to discharge ports and users
