革新和创制选矿设备,对促进有色金属生产发展有着重大意义。本刊本期发表的弧形筛、倾斜板式浓密箱、双盘强磁选机和浮选桂等四种新设备,就是近年来我国选矿设备改革中的一部分新的成就。这些设备的共同特点是从实际出发,解决实际问题,在生产中起到了很好的作用。例如,弧形筛找到了耐磨而又便宜的筛条材料,延长了使用寿命,由于应用了低压旋流给矿装置,提高了分级效率。倾斜板式浓密箱提高了浓密效率,減少了金属损失。φ576千武双盘强磁坊磁选机提高了磁坊强度,改善了分选效果,在结构上也做了不少有益的改进。浮选桂初步的解决了目前国外还没有解决的空气充气器问题,并基本上解决了自动控制问题。这些成绩是怎样取得的呢?最根本的原因是,高举毛泽东思想伟大红旗,敢于打破各种框框,学习与独创相结合,敢于创新,把改变我们一穷二白面貌、赶超世界先进水平的雄心壮志与发展我国有色金属工业紧密联系在一起,勇于闯出自己的发展道路。其次是,密切结合生产实际,有的放矢地、以解决生产实际问题和提高有色金属产量为目的,来创造选矿设备。第三,走群众路线,大搞群众性的技术革新和技术革命运动,创造新设备;科学研究部门下楼出院,加强协作,实行“三结合”。但是,还应该看到,有不少设备还没有配套成龙,潜力还没有充分发挥,仍然需要我们做艰苦的工作,进一步挖掘选矿设备的生产能力,希望各地选矿工作者,继续高举毛泽东思想伟大红旗,实现思想革命化,继续加强新设各的试验研究工作,为加速我国有色金属选矿工业的发展贡献力量。
Reform and creation of mineral processing equipment, to promote the development of non-ferrous metal production of great significance. This issue published in the arc sieve, inclined plate thick box, double disk magnetic separator and flotation Gui four new equipment, mineral processing equipment in China in recent years, part of the new achievements in the reform. The common feature of these devices is to proceed from reality, solve practical problems and play a very good role in production. For example, curved screens find wear-resistant and inexpensive screen materials that extend their useful life and improve classification efficiency due to the use of low-pressure swirl mills. Tilt platens increase dense efficiency and reduce metal loss. φ576 thousands of strong magnetic double Square magnetic separator to improve the magnetic field strength, improve the sorting results, in the structure also made a lot of useful improvements. Flotation Gui preliminary solution to the current foreign air inflator has not yet been solved, and basically solved the problem of automatic control. What are these achievements? The most fundamental reason is that they hold high the great red banner of Mao Zedong Thought, dare to break all kinds of frameworks, combine learning with creativity, dare to innovate, and change their ambidextrousness and ambition to catch up with and surpass the world’s advanced level. The development of China’s non-ferrous metals industry closely linked together, the courage to break the path of their own development. Second, in close connection with the actual production, with a definite aim, in order to solve the practical problems of production and increase non-ferrous metal production for the purpose of creating mineral processing equipment. Third, follow the mass line, engage in mass technological innovations and technological revolution campaigns, and create new equipment. The scientific research departments should be discharged from the hospital and intensified their cooperation to implement the “three unions.” However, we should also see that there are quite a few equipment that have not yet built up a complete set and the potential has not yet been fully tapped. We still need our hard work to further tap the production capacity of mineral processing equipment. We hope that the beneficiation workers everywhere will continue to hold high the great red banner of Mao Zedong Thought , To revolutionize the ideology, continue to strengthen the experimental work of the newly established, to speed up the development of China’s nonferrous metal beneficiation industry contribution.
