大红山铁矿石自磨试验研究

Autogenous Grinding of Dahongshan Iron Ores——A Test

以大红山铁矿石自磨介质适应性试验和半工业试验结果为依据，对自磨介质功指数、ＮＯＲＭ 基准数和流程试验结果进行了分析和讨论，结果表明，对大红山铁矿石可采用全自磨或半自磨，但采用半自磨工艺更为合理。

According to the results obtained by the adaptability test of autogenous grinding medium and the pilot test for Dahongshan iron ores, the authors analyse work indexes of autogenous grinding medium, NORM datum values and flowsheet test results and discuss the establishment of autogenous grinding technology and its flowsheet. The results show that it is more reasonable for the iron ores to adopt semi autogenous grinding technology.
