重介旋流器在我国选煤生产中的应用,已有十几年的历史。开始是用于选别末煤,以后发展到选跳汰机中煤。我国原煤中,难选煤比例较大。而我们现有选煤厂又大多以跳汰选为主,为了增加精煤回收,减少损失,提高选煤效率,除完善跳汰作业以外,用重介旋流器选跳汰机中煤是一条有效途径。可以预见,在老厂的技术改造中,用重介旋流器选跳汰机中煤,有着广阔的发展前途。
Dense medium cyclone in China’s coal preparation application, has more than 10 years of history. The beginning is used to select the end of the coal, after the election to the election jig in the coal. In China’s coal, the proportion of refractory coal is larger. However, most of our existing coal preparation plants mainly rely on jigging. In order to increase the recovery of clean coal, reduce losses and increase the efficiency of coal preparation, in addition to improving jig operations, coal in the jig An effective way. It is foreseeable that, in the technological transformation of the old factory, jigger jigging coal with a heavy medium cyclone has broad prospects for development.
