在选矿厂,磨矿分级过程是在碎矿和选别作业的中间,它的任务是把矿石中的有用矿物达到充分单体分离而又不产生过磨,为取得最高的选矿经济技术指标创造条件。由于磨矿分级过程的产品好坏对整个选矿厂的技术经济指标有决定性影响,设备投资费用在选矿厂全部投资中占有最大的比例,同时此过程还要消耗大量的电和磨矿介质如钢球等,因此对于如何充分发挥球磨分级设备的效率,提高磨矿分级产品的产量和质量,在国内外早就受到重视。
In the concentrator, grinding and grading process is in the middle of crushing and sorting operations, its task is to achieve the full separation of useful minerals in ore without over-grinding, in order to obtain the highest mineral processing economic and technical indicators to create condition. As the product of the grinding and grading process has a decisive influence on the technical and economic indicators of the entire concentrator, the investment cost of the equipment occupies the largest proportion of the total investment in the concentrator. At the same time, this process consumes a large amount of electricity and grinding media such as steel Ball and so on, so how to give full play to the efficiency of ball milling grading equipment to improve the output and quality of grinding and grading products, has long been valued at home and abroad.
