一、开滦选煤现状开滦矿务局现有炼焦煤选煤厂8座,年核定入洗能力1820万 t。在这8座选煤厂中,既有解放前的老设备,也有建国初期的旧设备,还有代表当今选煤先进技术水平的新设备。在选煤工艺上,开滦几乎具备了国内外所有的典型流程:跳汰—浮选流程(如林西、唐家庄、唐山、马家沟)、重介排矸—跳汰—浮选流程(如赵各庄)、块煤重介—末煤跳汰—浮选流程(如吕家坨、范各庄)和全重介—浮选流程(如钱家营)。这些流程的成功应用为中
First, the status of Kailuan Coal Preparation Kailu Mining Bureau existing coking coal preparation plant 8, the annual verification capacity 18.2 million t. In these 8 coal preparation plants, there are not only the old equipment before the liberation, but also the old equipment during the early years of the founding of the People’s Republic of China and the new equipment representing the advanced technological level of coal preparation today. In the process of coal preparation, Kailuan has almost all the typical processes at home and abroad: Jig - flotation processes (such as Linxi, Tangjiazhuang, Tangshan, Majiagou), heavy media gangue - Jig - flotation process Such as Zhao Gezhuang), lignite heavy medium - the end of the coal jig - flotation processes (such as Lv Tuo Tuo, Fan Gezhuang) and all heavy - flotation processes (such as money camp). The success of these processes is applied
