The system consists of a vibrating screen with a flexible screening deck, which removes the 0-10 mm fraction out of the dirty material stream.
The 0-10 mm fraction contains of a lot of fine glass, which causes enormous wear to the air system and should be determined out of the material stream before it reaches the wind shifter. Due to the fact that the unders fraction 0-10 mm is not cleaned by the wind shifter there will be small peaces of paper in this stream. Behind the vibrating screen there is a covered conveyor with a wind shifter positioned at the end with an integrated reception chute.
The next step in this cleaning process is a second vibrating screen with flexible screening deck. This screen removes the 10-25 mm fraction out of the material stream. After taking out this fraction a product remains, which is considerable heavier than the contaminations that still are in the material stream. At the end of this screen a second wind shifter with integrated reception chute is positioned. This wind shifter will take out the majority of the contaminations of 25-50 kg/m3.
