copyrighted photo From CWRN's new website showing a clearer pic of 3 screens feeding a hopper which apparently feeds a magnetic separator -I never understood why Bao (or other buyers) doesnt distinguish between .5-3mm which used to be the definition of sinter fines and the larger than 3mm "lumps''- as sinter fines usually require an extra step by the steelmaker before loading into the furnace-or does the buyer now prefer to separate the two themselves?
