A system for preparing coal blend with a water-oil emulsion comprising oil tank (1) and water tank (2) being pumped to an emulsion tank(5) for preparing water-oil emulsion, supplying emulsion from the emulsion tank to coal transfer hopper(8) having emulsion sprayers in the top region having a coal feeding conveyor(9) in the vicinity thereof, to obtain 0.03 wt.% oil and 0.18 wt.% water in form of emulsion in coal blend preferably following a method using said system, discharging the emulsion blended coal from the said hopper to a primary crusher(6) for effectively crushing the coal blend to finer coal, transporting the crushed blend to a pneumatic classifier(10), discharging fines from the pneumatic classifier as product and feeding the coarse grain from the pneumatic classifier to a second crusher(7) for crushing the coarse coat blend water-oil emulsion leaving the classifier into a finer grains, and for recycling the fine discharge therein.[IN222920A1]
