Beneficiation Technique Of Coal

Coal Beneficiation Iim

Raw coal fed on to the vibrating bed having crosswise and vertical slope. Air supplied through air holes in the beneficiation bed which agitates the raw coal resulting in stratification of coal as per its relative densities -lighter coal forms the upper layer and heavier coal forms the lower layer. Upper good coal
