淘汰盘在第一次世界大战前就应用于选煤,但除用于分选无烟末煤外,应用范围并不广泛。作为公用事业用煤,末烟煤往往由于卖不上价去,而作为废物舍弃。然而炼焦末煤,只要把杂质脱除,也能像块煤一样炼出优质焦炭。已证明,淘汰盘是精选炼焦末煤的一种高效设备,为此已得到越来越广泛的应用。 Out of the pan before the First World War should be applied to coal preparation, but except for the separation of smokeless coal, the scope of application is not extensive. As a utility coal, end-bituminous coal is often discarded as waste because it can not be sold at a higher price. However, the coking coal at the end, as long as the impurities removed, can also be the same as lump coal refining high-quality coke. It has been proved that the phase-out disk is an efficient device for selecting the coking coal at the end and has been used more and more widely for this purpose.
