煤泥是选煤厂排放的低热值尾料,我国每年排放煤泥约600万t.它颗粒细、持水性强、极易粘结,贮存和装运难度很大.长期以来,它的主要出路是供民用就地销售.但由于不便于远距离运输和长时间贮存,销路受到一定局限.随着洗选工业的发展,煤泥的年排放量也必然不断增加,充分利用这些煤泥并解决它的贮运问题,的确是一项势在必行的任务.
Slime is low-calorific value tailings discharged from the coal preparation plant. In our country, about 6 million tons of slime are discharged every year. Its fine grain, strong water holding capacity, extremely easy to bond, storage and shipment are very difficult. For a long time, its main outlet Is for civil on-site sales, but because of inconvenience for long-distance transport and storage for a long time, limited sales.With the development of the washing industry, the annual emissions of slime will inevitably continue to increase, make full use of these slime and solve Its storage and transportation problem is indeed an imperative task.
