铁矿粉 meaning in English
hematite
Examples
- Experimental research on sintering performances of imported powder iron ores with high and medium ignition loss
中高度烧损进口铁矿粉烧结性能试验研究 - It is indicated that since different kinds of iron ores have different self - characteristics , the sintering intensity of binding phase and its dependence on basicity have obvious difference
结果表明：不同种类的铁矿粉由于其自身特性的不同，所生成的烧结粘结相的强度以及随二元碱度的变化规律有明显差异。 - In sintering process , for melted mineral fines bind unmelted core ores when cooled , the self - intensity of binding phase in iron ores is one of the basic indexes to estimate sintered binding status
摘要在铁矿粉烧结过程中，熔化的矿粉在冷却过程中起著粘结周围未熔矿粉的作用，因此这一粘结相的自身强度是衡量烧结矿固结状况的重要指标之一。 - With eight kinds of iron ores , the self - intensity characteristic of binding phase was studied at the same temperature and different basicities and their influence factors were theoretically discussed
运用这一新概念，以八种常用的铁矿粉为对象，在固定温度、改变碱度的条件下进行了粘结相自身强度特性的实验研究，并对影响铁矿粉粘结相自身强度的因素进行了理论分析。 - An iron - containing material with an iron grade of over 20 % can be recovered from magnetic separation tailings of liuling iron mine by gravity method . this material can be used instead of partial clayey material to produce portland cement so as to reduce the mine tailings discharge amount to 43 . 52 % , to raise the iron recovery from 70 . 89 % to 84 . 62 % and to reduce the iron ore powder consumption in raw cement mixture and the energy consumption of raw material grinding
用重选法从刘岭铁矿磁选尾矿中回收铁矿物，可获得铁品位大于20 %的含铁物料，用此物料代替部分粘土质原料生产硅酸盐水泥，使矿山尾矿排放量减少至43 . 52 % ，铁的回收率由70 . 89 %提高到84 . 62 % ，并且减少了水泥生料配料中铁矿粉的用量，降低了生料粉磨能耗。
