国外有些国家广泛采用摇床,作为选别细粒级烟煤的主要分选设备。摇床选煤的优点逐渐被人们认识。我国要求使用摇床的选煤厂越来越多,但目前我国摇床选煤为数甚少,有些同志对摇床还不甚了解,因此有必要对摇床选煤的问题进行初步的探讨。我们希望能通过这篇文章起到抛砖引玉的作用,把我国未煤、粗煤泥精选和脱硫的工作做好,为加速实现四个现代化,赶超世界先进技术水平而努力。本文拟分三部分向读者介绍,即:平面摇床在选煤技术中的意义;平面摇床的原理、结构;影响摇床选煤的因素和摇床选煤工艺流程。
Some countries abroad widely use shaker, as the main sorting equipment for fine-grained bituminous coal. The advantages of shaker coal gradually recognized by people. There are more and more coal preparation plants in China that require the use of a shaker. However, there are only a few coal shakers in our country. Some comrades do not know much about the shaker. Therefore, it is necessary to conduct preliminary discussions on the issue of coal shaker. We hope that this article will serve as a valuable guide to our country’s unleaded coal, coarse slime selection and desulfurization work well in order to accelerate the realization of the four modern and catch up with the world’s advanced technology and work hard. This article will be divided into three parts to the reader, namely: the significance of the plane shaker in the coal preparation technology; plane shaker principle and structure; factors affecting shaker coal preparation and shaker coal preparation process.
