【摘要】：利用有色金属矿物在电磁波场中易产生热力耦合效应而降低其可碎性指标,对比研究了磁铁矿、黄铁矿、铀矿在不同电磁场作用下,对其内部微裂纹进行了分析研究,并对其破碎性能进行了实验研究。实验结果表明,电磁波预处理技术可以有效提高破碎流程的能力和效率,比如经电磁波场处理100s的黄铁矿,破碎设备可提高破碎能力50%以上。电磁波辅助破碎技术的经济性分析表明电磁波预处理技术可提高某些矿物的可破碎性能,该项技术在有色矿山具有较好的应用前景。
[Abstract]:In this paper, the thermal coupling effect of nonferrous metals in electromagnetic wave field is used to reduce its breakability. The internal microcracks of magnetite, pyrite and uranium ore under different electromagnetic fields are compared and studied. The crushing property was studied experimentally. The experimental results show that the technology of electromagnetic wave pretreatment can effectively improve the ability and efficiency of crushing process. For example, the crushing capacity of pyrite treated with electromagnetic wave field for 100 s can be increased by more than 50%. The economic analysis of electromagnetic wave assisted crushing technology shows that electromagnetic wave pretreatment technology can improve the breakability of some minerals, and this technology has a good application prospect in non-ferrous mines.
