Aluminium Trim Extraction  

The aluminium foil waste was collected from six sealing machines. The sealing machines punched out foil lids to be used on the steel containers. The web from the foil waste is continuous; therefore, it was imperative to cut the foil at the source before entering the pneumatic conveying system. Dedicated inline premium cutters were installed at each machine. The trim passes through the cutter connected up into the balanced ducting system, this is drawn into one single header of ducting and out to the external compactor.

Space was at a premium for the new aluminium trim extraction system. Therefore, as part of our design philosophy, it was based on a single new separator supported from a new frame with a multipurpose drop chute into the single compactor.

The design requires container changes and compactor maintenance with little stoppages in production. With this in mind, we designed an accumulation area within our system that will allow up to 4.8m3 of foil waste to collect while still operating, to not slow down production.
