coal mill technical parameters of various models

Coal beneficiation: Policy priorities for India | ORF

Coal Beneficiation is a process where coal is subjected to a medium of defined specific gravity. Heavier material sinks (rejects) and lighter coal floats (clean coal). This specific gravity is defined by the ''washability'' characteristics of the coal seam. It varies for different seams in the same area and for different geographical areas.
