针对南京吉山铁矿选厂湿式自磨生产实践中存在的主要问题,在吉山选厂大力支持下,我们进行了多次工业试验和室内研究,提高了自磨机生产能力,改进了自磨机排矿结构,提出了吉山选厂自磨改造的工艺流程,使难磨的硬质贫磁铁矿采用湿式自磨技术得到了较大改善。 Aiming at the main problems existing in the practice of wet self-grinding in Jishan iron ore processing plant in Nanjing, we conducted a number of industrial tests and laboratory studies with the strong support from the Jishan Flotation Plant to improve the self-mill production capacity and improve the self-mill Draining mine structure, put forward the technological process of Jishan dressing factory self-sharpening, and made hard-lean hard lean magnetite get a big improvement by wet self-grinding technology.
