原料煤中间密度磨碎—浮选的探索试验 -

原料煤的中间密度级(1.40~1.60kg/L和1.60~1.80kg/L)分别磨碎后,再进行筛分、浮沉、浮选试验,探索增加选煤厂精煤产率的可行性,以期达到充分利用煤炭资源的目的。 Medium density level(1.40~1.60kg/L and 1.60~1.80kg/L)of feed coal were grinded respectively,then carry out screening,floating,flotation test,explore the possibility in increasing clean coal yield of coal washery,in order to make full use of coal resources
