| 摘 要： | 采用微波高温箱式加热装置研究微波对惠民铁矿磨细的辅助作用。考察了该矿在微波场下的升温行为及微波加热对矿物孔隙率、内部裂隙及矿物磨细的影响。结果表明,惠民氧化铁矿在微波作用下能够在100s内被加热至600℃以上,并且微波处理后矿物孔隙率提高24.04%,相同磨矿条件下-200目产品的产率提高7.3%～11.3%,SEM微观结构物相分析显示微波处理后矿物产生大量的晶界间裂隙。

| Abstract: | The auxiliary function of microwave on the grinding of Huimin iron ore by microwave high-temperature heating device box was studied in the present paper.The temperature behavior of the iron ore in microwave field,the influence of microwave heating on the porosity,inherent vice and grinding of the iron ore were investigated.The results showed that the iron ore could be heated to above 600℃ quickly by microwave within 100s,and the porosity of the ore could be increased by 24.04% after microwave treatment.The yield of the sample below-200 mesh is increasing by 7.3%～11.3% at the same grinding condition.There was a large amount of crack generated between the grain boundary after the treatment as shown in the SEM image. |
