选矿是一门以试验为基础的应用科学,对于选矿而言没有现代化的试验设备,就难以完成复杂而艰巨的试验任务。为使我国选矿试验设备早日实现现代化,对于每个选矿工作者及从事选矿试验设备研究的同志,都应对选矿试验设备在选矿工业中的作用有一个全面的了解。为此,本文拟将选矿试验设备概况及其发展方向作以简介,以供参考。一、破碎筛分设备供选矿试验用的破碎设备主要是:颚式破碎机、辊式破碎机和研磨机。实验室型颚式破碎机是选矿试验及化验制样必不可少的常规设备。可是建国以来一直使用的是五十年代初期的落后产品。在使用的过程中暴露出了许多问题,如破碎间隙调节不便,破碎腔清扫不净,铸铁机壳易裂,大块矿石易反跳及成套性不好等缺陷。
Beneficiation is a pilot-based applied science that makes it difficult to accomplish complex and arduous testing tasks without the need for modern test equipment for mineral processing. In order to modernize the beneficiation test equipment in our country as soon as possible, we should have a comprehensive understanding of the role of beneficiation test equipment in the beneficiation industry for each beneficiation worker and comrades engaged in the research of beneficiation test equipment. For this reason, this article intends to introduce the general situation of the beneficiation test equipment and its development direction for reference. First, crushing and screening equipment for the beneficiation test crushing equipment used are: jaw crusher, roller crusher and grinding machine. Laboratory-type jaw crusher beneficiation test and laboratory sample preparation is essential conventional equipment. However, since the founding of the People's Republic of China, the backward products of the early 1950s have been used. During the process of using, many problems have been exposed, such as the inconvenience of adjusting the gap, the uncleanness of the crushing chamber, the easy cracking of the cast iron shell, the easy rebound of the big ore and the poor completeness of the complete set.
