It is used to segregate mostly plastics foils (2D) and solid parts (3D) streams. Wind blower are used to blow air against the falling material stream, then the 2D light parts will fly up over a splitter and following separated from the air stream. The 3D heavier parts fall below the splitter, through the air stream and onto the conveyor below.
Reduce wearing by air separation increase the lifetime.
Greater flexibility than mechanical separation systems
Dust emissions will be kept inside and separated.
