ABSTRACT:
Apparatus, methods and systems are used to separate fines from objects of a feed mixture being processed (e.g., iron bearing pellets, chips and dust). For example, at least a portion of an endless belt defining a channel is movable up an incline relative to horizontal (e.g., an incline that is at an angle relative to horizontal that is greater than an angle of repose associated with the objects, but less than an angle of repose associated with the fines being removed). Further, obstruction elements may be used on the endless belt to impede the flow of the fines down the incline.
