论文部分内容阅读
近几年来,各国非常重视选矿设备的研究和发展。在第十五届国际选矿会议上交流的论文中,有关设备研究共21篇,内容涉及分级、重选、磁选(超导和高梯度强磁选机)、浮选以及脱水设备的研制及使用情况。这些设备结构新颖,对各种矿物选别适应性强,并充分体现设计合理、节省能源等优点,对我国选矿设备发展很有参考价值。现简要介绍其中几种设备。一、多段离心分级机这种分级设备是芬兰奥托昆普公司近年来研制的一种新型结构,已用于磨矿回路中进行工业试验,取得较好结果。该机由多个水力旋流器组合成为一个整体,水力旋流器的圆筒部分互相连通,没有固定
In recent years, all countries attach great importance to the research and development of mineral processing equipment. In the fifteenth session of the International Conference on the exchange of papers, a total of 21 related equipment research, involving grading, re-election, magnetic separation (superconducting and high gradient magnetic separator), flotation and dewatering equipment development and Usage. These devices are novel in structure, adaptable to all kinds of minerals, and fully reflect the advantages of reasonable design and energy saving, which are very valuable for the development of mineral processing equipment in our country. Now briefly introduce several of these devices. First, multistage centrifugal classifier This grading equipment Finland Outokumpu company developed in recent years, a new type of structure, has been used in the grinding circuit for industrial testing, and achieved good results. The machine consists of a number of hydrocyclones combined into a whole, the hydrocyclone cylindrical part connected to each other, there is no fixed
