浅论我国冶金矿山选矿厂破碎系统的技术改造

Preliminary Discussion on the Technical Transformation of the Crushing System of the Metallurgical Mines,Concentrators in China

针对我国冶金矿山选矿厂破碎工序，尤其是细碎工序普遍存在的能耗高、效率低等问题，作者认为可以以国外引进关键的细碎设备，采用多碎少磨工艺，对现有破碎和磨矿回路统筹考虑进行技术改造。

In consideration of the problems of high energy consumption,low efficiency that generally exist in the crushing (especially the fine crushing operatoin) of China's metallurgical mines,concentrators,the author takes the opinion that key fine crushing equipment can be imported from abroad and the more crushing-less grinding technology be applied for the technical transformation of the crushing and grinding circuits of the existing concentrators which should be done in an overall planned.
