Improvement of output quality in film washing systems
The device reliably separates small hard contamination particles which are extremely difficult to remove using traditional methods within the washing line due to their specific density and size. These include in particular rigid plastic particles of PP or HDPE, and in addition light aluminium particles and small wood flakes.
The Film Examiner is mounted directly in the air stream after the thermal drying process, utilizing the different flow characteristics between small contamination and the light film flakes in order to achieve reliable separation. The air flow is adjustable by means of sliding gates in order to optimise the separation process. The contamination separated simply falls into the collection bin which can be easily monitored and emptied.
