摘要
介绍了传统碎矿磨矿设备的改进升级及高效磨碎设备的最新进展,如高压辊磨机、旋盘式破碎机、立磨机和艾萨磨机的应用。然后立足于中矿选择性分级再磨,对能简化碎磨工艺的"半自磨+立磨"和"破碎+棒磨+球磨"两种具有代表性的流程作了分析。最后从最佳入磨粒度,磨矿介质的尺寸、级配、形状、材质、充填率、助磨剂及磨矿产品中间易选粒级含量和回收率的多元线性回归模型等方面阐述了碎磨工艺参数方面取得的系统化的研究进展及应用。
This paper introduced the update and upgrade of traditional crushing and grinding equipment and its latest development research, such as the application of high-pressure grinding roller, rotary crusher, verti-mill and ISA mill. Then based on the ore selective classification regrinding, the two kinds of typical processes were analyzed and remarked, studied on process flows of＂semi self mill＋vertimill＂and＂crusher＋rod mill＋ball mill＂which can simplify the process flow of crushing and grinding. Finally, the research progresses improvement and applications were expounded from the best feed of grinding, size, proportion, shape and material of grinding media, filling ratio, grinding aids additives and the multiple linear regression model of recovery, easy dressing fraction＇s and others.
