近年来,随着我国有色金属工业的发展,选矿机械也有了很大的发展。选矿设备制造质量和机械效率不断提高,新机器不断诞生。现在,新建的一般大型的选矿厂已经完全可以用自己制造的设备装备起来,这是很大的成绩。但是,选矿设备的发展,目前还远远不能满足生产不断发展的要求,与世界先进技术水平相比,也还有一段不小的差距。这主要表现在:选矿设备质量还不够高,效率还比较低,品种规格也比较单一。特别是在选别 In recent years, with the development of China’s nonferrous metal industry, mineral processing machinery has also made great progress. Beneficiation equipment manufacturing quality and mechanical efficiency continue to increase, the new machine is constantly born. Now, the newly built general large-scale concentrator can already be equipped with the equipment they manufacture, which is a great achievement. However, the development of beneficiation equipment is still far from meeting the requirements of the continuous development of production. Compared with the world’s advanced technology, there is still a long way to go. This is mainly manifested in: dressing equipment quality is not high enough, the efficiency is still relatively low, the variety specifications are relatively simple. Especially in the election
