超细颗粒误置现象的存在降低了选煤厂设备的分离效率。虽然在1970年和1980年代认为细煤分级满足了选煤工作的需要,但是很明显选煤厂在产率/灰分/水分关系方面的改进仍有待于分级阶段效率的进一步提高。本文描述了克服此问题的现有的和正在开发的技术。
The existence of ultrafine particles misplacing reduces the separation efficiency of coal preparation plant. Although the classification of fine coal met the need for coal preparation in the 1970s and 1980s, it is clear that the improvement of the yield / ash / moisture relationship at the coal preparation plant remains to be further enhanced in the classification stage. This article describes existing and developing technologies that overcome this problem.
